Asias He 6f04de3efd streaming: Fail stream plan on stream_mutation_fragments handler in case of error
The following is observed in pytest:

1) node1, stream master, tried to pull data from node3

2) node3, stream follower, found node1 restarted

3) node3 killed the rpc stream

4) node1 did not get the stream session failure message from node3. This
failure message was supposed to kill the stream plan on node1. That's the
reason node1 failed the stream session much later at "2024-08-19 21:07:45,539".
Note, node3 failed the stream on its side, so it should have sent the stream
session failure message.

```

```

To be safe in case the stream fail message is not received, node1 could fail
the stream plan as soon as the rpc stream is aborted in the
stream_mutation_fragments handler.
