xfs: introduce xfs_bmapi_delay()
Delalloc reservations are much simpler than allocations, so give them a separate bmapi-level interface. Using the previously added xfs_bmapi_reserve_delalloc we get a function that is only minimally more complicated than xfs_bmapi_read, which is far from the complexity in xfs_bmapi. Also remove the XFS_BMAPI_DELAY code after switching over the only user to xfs_bmapi_delay. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Alex Elder <aelder@sgi.com>
