ivshmem: use kvm irqfd for msi notifications
Use irqfd for improving context switch when notifying the guest. If the host doesn't support kvm irqfd, regular msi notifications are still supported. Note: the ivshmem implementation doesn't allow switching between MSI and IO interrupts, this patch doesn't either.
