virtio: Redefine vring_avail_eventColibri-VF61-M4_FreeRTOS_1.2-20170407

Redefine vring_avail_event to avoid accessing ring.id as
a 16bit integer and breaking the C aliasing rules.

This fixes a build warning:
virtio/virtqueue.c: In function ‘vq_ring_must_notify_host’:
virtio/virtqueue.c:658:9: warning: dereferencing type-punned pointer will break
strict-aliasing rules [-Wstrict-aliasing]
         event_idx = vring_avail_event(&vq->vq_ring);
         ^

No functional change.
