If simultaneous NMIs happen, we're supposed to queue the second and next (collapsing them), but currently we sometimes collapse the second into the first. Fix by using a counter for pending NMIs instead of a bool; since the counter limit depends on whether the processor is currently in an NMI handler, which can only be checked in vcpu context (via the NMI mask), we add a new KVM_REQ_NMI to request recalculation of the counter.
