Xie Yongji 72b736153e vm-virtio: Fix update_avail_event() memory ordering 
We should use full memory barrier to ensure both guest and us
can see the correct avail_idx and avail_event_idx. Something
like this pattern:

VM:                           CLH:
update vring.avail->idx       update avail_event_idx
mb()                          mb()
read avail_event_idx          read vring.avail->idx
