We can't allow overlapped locked ranges - otherwise two different channels could be deadlocked. So add a pending_locked_ranges to the bdev. When we start a lock operation, check if the new range overlaps one that's already locked. If so, put it on the pending list. When an unlock operation completes, we will check if any pending ranges can now be locked.
