Ok, Here's a "pass-in-the-shutdown-method" version of the change.

xfs: pass shutdown method into xfs_trans_ail_delete_bulk
From: Dave Chinner <dchinner@xxxxxxxxxx>
xfs_trans_ail_delete_bulk() can be called from different contexts so
if the item is not in the AIL we need different shutdown for each
context. Pass in the shutdown method needed so the correct action
can be taken.
