Sebastien Boeuf be421dccea vm-virtio: Optimize vhost-user interrupt notification
Thanks to the recently introduced function notifier() in the
VirtioInterrupt trait, all vhost-user devices can now bypass
listening onto an intermediate event fd as they can provide the
actual fd responsible for triggering the interrupt directly to
the vhost-user backend.

In case the notifier does not provide the event fd, the code falls
back onto the creation of an intermediate event fd it needs to listen
to, so that it can trigger the interrupt on behalf of the backend.
