When commit e64309198eda2 ("KVM: arm64: Turn vcpu->arch.pause into a counter") changed the type of kvm_vcpu_arch.pause from bool to atomic_t, the merge into this tree missed the s390 copy, leaving it out of sync. Nothing on the s390 side accesses vcpu->arch.pause yet, so this has no functional effect. Align the type to keep the mirror identical to its arm64 counterpart.
