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.
