KVM: x86: count actual tlb flushes
- we count KVM_REQ_TLB_FLUSH requests, not actual flushes
(KVM can have multiple requests for one flush)
- flushes from kvm_flush_remote_tlbs aren't counted
- it's easy to make a direct request by mistake
Solve these by postponing the counting to kvm_check_request().
