Test failure: SocketBlockingModeTransitionTests.ConnectAsync_WithBuffer_Succeeds fails intermittently on Linux

## Test failure

`System.Net.Sockets.Tests.SocketBlockingModeTransitionTests.ConnectAsync_WithBuffer_Succeeds` is failing intermittently on **Linux** (`Ubuntu.2604.Amd64.Open`, `Alpine.324.Amd64.Open`, `Alpine.Edge.Amd64.Open`, `AzureLinux.3.0.ArmArch.Open`, `Alpine.324.Arm64.Open`) in the inner loop across the `runtime`, `runtime-coreclr crossgen2`, and `runtime-nativeaot-outerloop` pipelines.

### Error message

```
Assert.False() Failure
Expected: False
Actual: True
```

Stack trace:

```
at System.Net.Sockets.Tests.SocketBlockingModeTransitionTests.ConnectAsync_WithBuffer_Succeeds() in /_/src/libraries/System.Net.Sockets/tests/FunctionalTests/Connect.Unix.cs:line 230
```

### Frequency

11 builds on **main** plus ~34 PR runs over the past 14 days, exclusively on Linux queues. Ongoing since 2026-08-19.

## Analysis

The failing assertion is at `Connect.Unix.cs:230`:

`src/libraries/System.Net.Sockets/tests/FunctionalTests/Connect.Unix.cs`

```csharp
bool completedAsync = client.ConnectAsync(saea);
if (!completedAsync)
{
tcs.SetResult();
}

await tcs.Task;

Assert.Equal(SocketError.Success, saea.SocketError);
Assert.True(client.Blocking);

// On Apple and Android platforms, TFO (connectx/sendto) may complete the connect+send
// in a single syscall, so the socket can end up blocking even on the async path.
// On Linux, async connect always leaves the socket non-blocking when
// buffer > 0 because SendToAsync is pending.
if (!completedAsync || PlatformDetection.IsApplePlatform || PlatformDetection.IsAndroid)
{
Assert.False(IsSocketNonBlocking(client)); // <-- line 230
}
else
{
Assert.True(IsSocketNonBlocking(client));
}
```

On loopback the `ConnectAsync(saea)` with a send buffer can complete **synchronously** (`completedAsync == false`). The test then takes the line-230 branch and asserts the socket has been restored to **blocking** mode (`IsSocketNonBlocking == False`). Intermittently the socket is still **non-blocking** (`Actual: True`), because a pending async send left over from the connect+send path keeps the descriptor in non-blocking mode.

In other words, the test's assumption that a synchronously-completing `ConnectAsync` + buffer always restores blocking mode does not hold on Linux loopback: the sync-vs-async classification races with whether the underlying `SendToAsync` is still pending. This looks like a **test-logic race** (the `!completedAsync` branch is not a reliable proxy for "the socket has been restored to blocking mode"), though it may also point at a blocking-mode-restore gap in the sync-completion path.

## Suggested fix

Make the blocking-mode assertion tolerant of the sync-completion-with-pending-send case on Linux (e.g. only assert blocking mode when there is genuinely no pending send), or restore blocking mode deterministically before completing the synchronous connect+send path. Until then, filing a Known Build Error so Build Analysis can auto-match this failure.
