thermal: gov_power_allocator: Add missing NULL pointer check
commit ac1f43c03fc91eee53cc95683245350d4d87781e upstream.
Commit 0dc23567c206 ("thermal: core: Move lists of thermal instances
to trip descriptors") overlooked the case in which the Power Allocator
governor attempts to bind to a tripless thermal zone and params->trip_max
is NULL in check_power_actors().
No power actors can be found in that case, so check_power_actors() needs
to be made return 0 then to restore its previous behavior.
Fixes: 0dc23567c206 ("thermal: core: Move lists of thermal instances to trip descriptors")
