target/s390x: interpret PSW_MASK_WAIT only for TCG
KVM handles the wait PSW itself and triggers a WAIT ICPT in case it
really wants to sleep (disabled wait).
This will later allow us to change the order of loading a restart
interrupt and setting a CPU to OPERATING on SIGP RESTART without
changing KVM behavior.
