The current use of KVM_REQ_VCPU_EXIT for pause is fine. Even the requester clearing the request is OK, as this is the special case where the sole requesting thread and receiving VCPU are executing synchronously (see "Clearing Requests" in Documentation/virtual/kvm/vcpu-requests.rst) However, that's about to change, so let's ensure only the receiving VCPU clears the request. Additionally, by guaranteeing KVM_REQ_VCPU_EXIT is always set when pause is, we can avoid checking pause directly in VCPU RUN.
