librbd: inform the journal when pending IO safely commits
When caching is disabled, the AioCompletion notifies the journal that
the update is safe. When caching is enabled, writeback can result
in partial write extents being overwritten (and no longer associated
to the original journal event). In this case, the writeback handler
is responsible for informing the journal when writes are safe.
