[PATCH] macintosh: ams: replace snprintf in show functions with sysfs_emit

[Qing Wang]

show() must not use snprintf() when formatting the value to be
returned to user space.

Fix the following coccicheck warning:
drivers/macintosh/ams/ams-core.c:53: WARNING: use scnprintf or sprintf.

Use sysfs_emit instead of scnprintf or sprintf makes more sense.
