[PATCH 55/64] xfs: don't bother calling xfs_refcount_finish_one_cleanup in xfs_refcount_finish_one

["Darrick J. Wong" <djwong@xxxxxxxxxx>]

From: Darrick J. Wong <djwong@xxxxxxxxxx>

Source kernel commit: bac3f784925299b5e69a857e7e03e59c88aa14be

In xfs_refcount_finish_one we know the cursor is non-zero when calling
xfs_refcount_finish_one_cleanup and we pass a 0 error variable.  This
means xfs_refcount_finish_one_cleanup is just doing a
xfs_btree_del_cursor.

Open code that and move xfs_refcount_finish_one_cleanup to
fs/xfs/xfs_refcount_item.c.
