[PATCH V2 4/5] hid-sensor: replace snprintf in show functions with sysfs_emit

show() should not use snprintf() when formatting the value to be returned 
to user space, snprintf() returns the length the resulting string and 
scnprintf() returns the number of bytes printed into the buffer.

Fix the coccicheck warnings:
WARNING: use scnprintf or sprintf.

Use sysfs_emit() instead of scnprintf() makes more sense.
