cpu: Replace qemu_for_each_cpu()
It was introduced to loop over CPUs from target-independent code, but
since commit 182735efaf956ccab50b6d74a4fed163e0f35660 target-independent
CPUState is used.
A loop can be considered more efficient than function calls in a loop,
and CPU_FOREACH() hides implementation details just as well, so use that
instead.
