xfs: drop dquot flush lock when we can't find a buffer to flush

Browse source

LOLLM noticed that xfs_qm_flush_one fails to drop the dquot flush lock
if it can't grab the buffer associated with the dquot.  Since there's no
buffer, nobody else is going to drop the dqflock, so we need to do it
ourselves.
