drbd: silence some noisy log messages during disconnect
If we fail to send the information that we lost our disk,
we have no connection, and no disk: no access to data anymore.
That is either expected (deconfiguration), or there will be so much
noise in the logs that "Sending state failed" is not useful at all.
Drop it.
If the reason for a shorter than expected receive was a signal,
which we sent because we already decided to disconnect,
these additional log messages are confusing and useless.
This patch follows this pattern:
- dev_warn(DEV, "short read expecting header on sock: r=%d\n", r);
+ if (!signal_pending(current))
+ dev_warn(DEV, "short read expecting header on sock: r=%d\n", r);
Also make them all dev_warn for consistency.
