Lars Ellenberg 20004e2435 drbd: bump current uuid when resuming IO with diskless peer
Scenario, starting with normal operation
 Connected Primary/Secondary UpToDate/UpToDate
 NetworkFailure Primary/Unknown UpToDate/DUnknown (frozen)
 ... more failures happen, secondary loses it's disk,
 but eventually is able to re-establish the replication link ...
 Connected Primary/Secondary UpToDate/Diskless (resumed; needs to bump uuid!)

We used to just resume/resent suspended requests,
without bumping the UUID.

Which will lead to problems later, when we want to re-attach the disk on
the peer, without first disconnecting, or if we experience additional
failures, because we now have diverging data without being able to
recognize it.

Make sure we also bump the current data generation UUID,
if we notice "peer disk unknown" -> "peer disk known bad".
