hw/s390x/s390-virtio-ccw: Fix a record/replay deadlock
Booting an s390x VM in record/replay mode hangs due to a deadlock between rr_cpu_thread_fn() and s390_machine_reset(). The former needs the record/replay mutex held by the latter, and the latter waits until the former completes its run_on_cpu() request. Fix by temporarily dropping the record/replay mutex, like it's done in pause_all_vcpus().
