[PATCH 06/12] xfs: convert xfs_da_do_buf to use irec buffer interface

[Dave Chinner]

From: Dave Chinner <dchinner at redhat.com>

Convert xfs_da_do_buf to use ithe new irec buffer interface. This is
just a simple 1:1 conversion as the irec interface only support
single maps at this point in time.
