[COMMIT master] KVM: use POLLHUP to close an irqfd instead of an explicit ioctl

From: Gregory Haskins Assigning an irqfd object to a kvm object creates a relationship that we currently manage by having the kvm oject acquire/hold a file* reference to the underlying eventfd. The lifetime of these objects is properly maintained by decoupling the two objects whenever the irqfd
