nilfs2: replace snprintf in show functions with sysfs_emit

[ Upstream commit 3bcd6c5bd483287f4a09d3d59a012d47677b6edc ]

Patch series "nilfs2 updates".

This patch (of 2):

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.
