[PATCH 28/67] xfs: pass the defer ops directly to xfs_defer_add

From: Christoph Hellwig <hch@lst.de>

Source kernel commit: 603ce8ab12094a2d9483c79a7541335e258a5328

Pass a pointer to the xfs_defer_op_type structure to xfs_defer_add and
remove the indirection through the xfs_defer_ops_type enum and a global
table of all possible operations.
