xfs: replace snprintf in show functions with sysfs_emit
coccicheck complains about the use of snprintf() in sysfs show functions. Fix the coccicheck warning: WARNING: use scnprintf or sprintf. Use sysfs_emit instead of scnprintf or sprintf makes more sense. Signed-off-by: Qing Wang <wangqing@vivo.com> Reviewed-by: Darrick J. Wong <djwong@kernel.org> Signed-off-by: Darrick J.
