xfs: factor out quotaoff intent AIL removal and memory free
AIL removal of the quotaoff start intent and free of both intents is hardcoded to the ->iop_committed() handler of the end intent. Factor out the start intent handling code so it can be used in a future patch to properly handle quotaoff errors. Use xfs_trans_ail_remove() instead of the _delete() variant to acquire the AIL lock and also handle cases where an intent might not reside in the AIL at the time of a failure.
