Janis Schoetterl-Glausch 54354861d2 target/s390x: kvm: Honor storage keys during emulation
Storage key controlled protection is currently not honored when
emulating instructions.
If available, enable key protection for the MEM_OP ioctl, thereby
enabling it for the s390_cpu_virt_mem_* functions, when using kvm.
As a result, the emulation of the following instructions honors storage
keys:

* CLP
  	The Synch I/O CLP command would need special handling in order
  	to support storage keys, but is currently not supported.
* CHSC
	Performing commands asynchronously would require special
	handling, but commands are currently always synchronous.
* STSI
* TSCH
	Must (and does) not change channel if terminated due to
	protection.
* MSCH
	Suppressed on protection, works because fetching instruction.
* SSCH
	Suppressed on protection, works because fetching instruction.
* STSCH
* STCRW
	Suppressed on protection, this works because no partial store is
	possible, because the operand cannot span multiple pages.
* PCISTB
* MPCIFC
* STPCIFC
