thermal: gov_power_allocator: Eliminate a redundant variable
Notice that the passive field in struct thermal_zone_device is not
used by the Power Allocator governor itself and so the ordering of
its updates with respect to allow_maximum_power() or allocate_power()
does not matter.
Accordingly, make power_allocator_manage() update that field right
before returning, which allows the current value of it to be passed
directly to allow_maximum_power() without using the additional update
variable that can be dropped.
