xfs: clean up xfs_buf_item_get_format return value
The only thing that can cause a nonzero return from xfs_buf_item_get_format is if the kmem_alloc fails, which it can't. Get rid of all the unnecessary error handling. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Reviewed-by: Christoph Hellwig <hch@lst.de>
