[PATCH 1/3] KVM: s390: arm64: Turn vcpu->arch.pause into a counter

[Andreas Grapentin <gra@linux.ibm.com>]

From: Steffen Eiden <seiden@linux.ibm.com>

The s390 arm64 vcpu struct mirrors arm64's kvm_vcpu_arch. 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.

Fixes: e6c329180d1d ("KVM: s390: arm64: Introduce host definitions")
