[Qemu-devel] [PATCH 02/17] monitor: Use qemu_get_cpu() in monitor_set_cpu()

[Andreas Färber]

No functional change, just a reduction of CPU loops.

The mon_cpu field is left untouched for now since changing that requires
a number of larger prerequisites, including cpu_synchronize_state() and
mon_get_cpu().
