[BUG] Corrupted CAN frame from network upperhalf / network stack

### Description / Steps to reproduce the issue

When testing mpfs mss_can.c, I encountered this weird issue with corrupted frame received from upperhalf. I would say about 10% defection. The CAN ID is always either corrupted to 0x0 or 0xC2008020.
This happens only protected mode not flat mode.
The issue was first noted in https://github.com/apache/nuttx/pull/17161
How to reproduce:
1. build nuttx in protected mode with DEBUG_NET_INFO, DEBUG_NET_WARN, DEBUG_NET_ERROR enabled and CONFIG_CANUTILS_CANSEND enabled in nuttx apps
2. `ifup can0` , `cansend can0 123#deadbeef` and observe some randomly corrupted frames as folllowing
```
saluki> cansend can0 123#deadbeef
[CPU0] mpfs_transmit: TX Frame: ID=0x0, DLC=0
[CPU0] mpfs_transmit: TX Debug: cf.can_id=0x0, msg_id=0x0, shifted=0x0, DLC=0
[CPU0] mpfs_transmit: TX HW Write: addr=0x2010C020, ID_reg=0x0, data_high=0x0, data_low=0x0

```
Upon closer inspection, the corruption already happens in network stack. Suspected at:
```
User space: cansend → write() → sendmsg()
↓ (system call boundary)
Kernel space: sendmsg() → psock_sendmsg() → can_sendmsg()
↓
can_sendmsg(): devif_send(dev, pstate->snd_buffer, ...)
↓
devif_send(): iob_trycopyin(dev->d_iob, buf, len, offset, false)
↓
iob_trycopyin(): iob_copyin_internal(...)
↓
iob_copyin_internal(): memcpy(dest, src, ncopy) ← **FAILURE POINT**
```

### Verification

- [x] I have verified before submitting the report.

Start with mss_can.c and reproduce the corruption in protected mode using the listed DEBUG_NET options and cansend command. Trace the mentioned path from can_sendmsg() through devif_send(), iob_trycopyin(), and iob_copyin_internal(), comparing it with flat mode. Done means repeated CAN transmissions no longer produce corrupted IDs or DLC values in the provided logs.

Written by the indexing model from the issue text.
