thermal: gov_power_allocator: Fix incorrect calculation in divvy_up_power()

divvy_up_power() should use weighted_req_power instead of req_power to
calculate granted_power. Otherwise, granted_power may be unexpected as
the denominator total_req_power is a weighted sum.

This is a mistake made during the previous refactor.

Replace req_power with weighted_req_power in divvy_up_power()
calculation.
