s390x/tcg: simplify machine check handling
We currently only support CRW machine checks. This is a preparation for
real floating interrupt support.
Get rid of the queue and handle it via the bit INTERRUPT_MCHK. We don't
rename it for now, as it will be soon gone (when moving crw machine checks
into the flic).
Please note that this is the same way also KVM handles it: only one
instance of a machine check can be pending at a time. So no need for a
queue.
While at it, make sure we try to deliver only if env->cregs[14]
actually indicates that CRWs are accepted.
Drop two unused defines on the way (we already have PSW_MASK_...).
