KVM: s390: Restore sigset on error path
kvm_sigset_activate() installs vcpu->sigset via sigprocmask() and
stashes the caller's mask in current->real_blocked; only
kvm_sigset_deactivate() restores it.
For KVM_RUN on a STOPPED vcpu the error path will not restore the
userspace mask. Re-arrange the error handling to also restore the
signal mask.
Fixes: 6352e4d2dd9a3 ("KVM: s390: implement KVM_(S|G)ET_MP_STATE for user space state control")
