[PATCH] netfilter: xt_IDLETIMER: replace snprintf in show functions with sysfs_emit

[cgel . zte]

From: Jing Yao <yao.jing2@xxxxxxxxxx>

coccicheck complains about the use of snprintf() in sysfs show
functions:
WARNING use scnprintf or sprintf

Use sysfs_emit instead of scnprintf, snprintf or sprintf makes more
sense.
