KVM: s390: rewrite vcpu_post_run and drop out early
Let's rewrite this function to better reflect how we actually handle exit_code. By dropping out early we can save a few cycles. This especially speeds up sie exits caused by host irqs. Also, let's move the special -EOPNOTSUPP for intercepts to the place where it belongs and convert it to -EREMOTE.
