ci/lava: Detect R8152 issues preemptively and retry

Implement a log-based retry hint for R8152 issue described in #6681,
which is based on detecting these two consecutive lines:

```
r8152 <USB> eth0: Tx status -71
nfs: server <IP> not responding, still trying
```

Where <IP> and <USB> could be any IP and USB addresses, respectfully.

This commit is a temporary fix since it requires a section-aware log
follower, implemented in !16323. When the cited MR is merged, one will
make a proper fix on top of that.

Closes: #6681
