KVM: s390: Clear valid_wakeup in kvm_s390_handle_wait(), not in arch hook
Move the clearing of valid_wakeup from kvm_arch_vcpu_block_finish() so
that a future patch can drop said arch hook. Unlike the other blocking-
related arch hooks, vcpu_blocking/unblocking(), vcpu_block_finish() needs
to be called even if the KVM doesn't actually block the vCPU. This will
allow future patches to differentiate between truly blocking the vCPU and
emulating a halt condition without introducing a contradiction.
Alternatively, the hook could be renamed to kvm_arch_vcpu_halt_finish(),
but there's literally one call site in s390, and future cleanup can also
be done to handle valid_wakeup fully within kvm_s390_handle_wait() and
allow generic KVM to drop vcpu_valid_wakeup().
No functional change intended.
