drbd: Fixes from the drbd-8.3 branch
* drbd-8.3:
drbd: fix spurious meta data IO "error"
drbd: Fixed a race condition between detach and start of resync
drbd: fix harmless race to not trigger an ASSERT
drbd: Derive sync-UUIDs only from the bitmap-uuid if it is non-zero
drbd: Fixed current UUID generation (regression introduced recently, after 8.3.11)
