thermal: Only set passive_delay for forced_passive cooling
Setting polling_delay is useless as passive_delay has priority,
so the value shown in proc isn't the actual polling delay. It
also gives the impression to the user that he can change the
polling interval through proc, while in fact he can't.
Also, unset passive_delay when the forced passive trip point is
unbound to allow polling to be disabled.
