librbd: directly inform IO work queue when locks are required
Due to lock dependency issues between librbd locks and the the thread
pool lock, it's impossible to directly determine if the lock is
required within the _void_dequeue method. Therefore, this state needs
to be internally tracked by the work queue.

@trociny Fixed two bugs (1) disabling the journal was never destroying the Journal object and (2) I accidentally broke the blocked write handling. The changes are in the last two commits.
