sched/fair: Fix load_above_capacity fixed point arithmetic width
Since commit:
2159197d6677 ("sched/core: Enable increased load resolution on 64-bit kernels")
we now have two different fixed point units for load.
load_above_capacity has to have 10 bits fixed point unit like PELT,
whereas NICE_0_LOAD has 20 bit fixed point unit on 64-bit kernels.
Fix this by scaling down NICE_0_LOAD when multiplying
load_above_capacity with it.
