Dmitry Torokhov 8ff21f44fa Input: fix used slots detection breakage 
Commit f8ec894945 allowed external callers
use slot dropping logic, unfortunately it also broke external users of
input_mt_is_used() as we stopped incrementing frame count unless input
device was set up to automatically drop unused slots.

Fixes: f8ec894945 ("Input: MT - make slot cleanup callable outside
mt_sync_frame()")
