This doesn't really fix anything as rte_vhost
logging functions are extremely poorly designed
and do smp_wmb() by themselves - but only if
logging is enabled...
Let's move the barrier in our vhost.c. This
doesn't change any behavior, but makes the code
more readable. It surely looked weird to update
the ring, log it, and then do smp_wmb().
