sched/fair: Use full weight to __calc_delta()
Since we now use the full weight for avg_vruntime(), also make
__calc_delta() use the full value.
Since weight is effectively NICE_0_LOAD, this is 20 bits on 64bit.
This leaves 44 bits for delta_exec, which is ~16k seconds, way longer
than any one tick would ever be, so no worry about overflow.
