Since guest_mask_notifier can not be used in vhost-user mode due to buffering implied by unix control socket, force use_mask_notifier on virtio devices of vhost-user interfaces, and send correct callfd to the guest at vhost start. Using guest_notifier_mask function in vhost-user case may break interrupt mask paradigm, because mask/unmask is not really done when returning from guest_notifier_mask call, instead message is posted in a unix socket, and processed later. Add an option boolean flag 'use_mask_notifier' to disable the use of guest_notifier_mask in virtio pci.
