Convert all the code to just return the error directly and use XFS_WANT_CORRUPTED_RETURN. This also allows the final call to xfs_bmbt_update() to return directly. Noticed while reviewing coccinelle return cleanup patches and wondering why the same return pattern as in xfs_bmse_shift_one() wasn't picked up by the checker pattern...
