[PATCH 02/26] libxfs: remove LIBXFS_EXIT_ON_FAILURE

["Darrick J. Wong" <darrick.wong@xxxxxxxxxx>]

From: Darrick J. Wong <darrick.wong@xxxxxxxxxx>

Now that the read-side users of LIBXFS_EXIT_ON_FAILURE are gone and the
only write-side callers are in mkfs which now checks for buffer write
failures, get rid of LIBXFS_EXIT_ON_FAILURE.
