Fluentd agent completely stuck due to printing "pattern not match warning"

### Describe the bug

Hi Team,

We observed that when Fluentd agent is overwhelmed with "pattern not matched:" warning after some time it gets stuck and stopped processing. Both tailing and flushing buffers are stuck.

### To Reproduce

To reproduce this issue we run an experiment on shared configuration.

```
Case1:
Fluentd agent running fine and able to process incoming logs file heartbeat.log.
```
```
Case 2:
In addition to case 1, we started appending logs to file pattern_not_match.log which will result in pattern not match warning and overwhelmed files with new logs. After some time agent got stuck and stopped processing logs from the heartbeat.log file.
we stopped adding log line to pattern_not_match.log but the agent didn't recover from the stuck state.
```

```
Case3: manually commented https://github.com/fluent/fluentd/blob/master/lib/fluent/plugin/in_tail.rb#L640 to stop printing pattern not match warning, and restarted agent. and repeated case 2. The agent was running fine and pattern not warning not impacting fluentd now.
```

For each case, the sig dump is attached.

Case 1 : 6:55 AM to 8:10AM
Case 2: 8:10 AM to 9:15AM
case 3 : 9:15 AM to continue

Sigdump atteched below.

### Expected behavior

The agent should not go into a stuck state.
Why print log line with pattern not match warning resulting in this issue? @ashie can you look into this?
