[PATCH] btrfs: replace snprintf in show functions with sysfs_emit

[Qing Wang]

coccicheck complains about the use of snprintf() in sysfs show functions.

Fix the following coccicheck warning:
fs/btrfs/sysfs.c:335:8-16: WARNING: use scnprintf or sprintf.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
