xfs: combine xfs_trans_ail_[remove|delete]()
Now that the functions and callers of xfs_trans_ail_[remove|delete]() have been fixed up appropriately, the only difference between the two is the shutdown behavior. There are only a few callers of the _remove() variant, so make the shutdown conditional on the parameter and combine the two functions.

-/**
- * Remove a log items from the AIL
- *
- * @xfs_trans_ail_delete_bulk takes an array of log items that all need to
- * removed from the AIL. The caller is already holding the AIL lock, and done
- * all the checks necessary to ensure the items passed in via @log_items are
- * ready for deletion. This includes checking that the items are in the AIL.
- *
- * For each log item to be removed, unlink it from the AIL, clear the IN_AIL
- * flag from the item and reset the item's lsn to 0. If we remove the first
- * item in the AIL, update the log tail to match the new minimum LSN in the
- * AIL.
- *
- * This function will not drop the AIL lock until all items are removed from
- * the AIL to minimise the amount of lock traffic on the AIL. This does not
- * greatly increase the AIL hold time, but does significantly reduce the amount
- * of traffic on the lock, especially during IO completion.
- *
- * This function must be called with the AIL lock held. The lock is dropped
- * before returning.
