f2fs: replace snprintf in show functions with sysfs_emit
coccicheck complains about the use of snprintf() in sysfs show functions. Fix the following coccicheck warning: fs/f2fs/sysfs.c:198:12-20: WARNING: use scnprintf or sprintf. fs/f2fs/sysfs.c:247:8-16: 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: Chao Yu <chao@kernel.org> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
