tuner: return number of instances remaining after hybrid_tuner_release_state
From: Michael Krufky <mkrufky@linuxtv.org>
Assign the number of instances remaining as the return value of
hybrid_tuner_release_state, in case there is any extra cleanup that
the tuner driver needs to do after an instance has been destroyed.
