[RFC 37/60] cosched: Use hrq_of() for (indirect calls to) ___update_load_sum()

[Jan H. SchÃnherr]

The cpu argument supplied to all callers of ___update_load_sum() is used
in accumulate_sum() to scale load values according to the CPU capacity.
While we should think about that at some point, it is out-of-scope for now.
Also, it does not matter on homogeneous system topologies.

Update all callers to use hrq_of() instead of rq_of() to derive the cpu
argument.
