This is suggested by Michael S. Tsirkin according to [1] and the goal
is to apply smp_rmb() inside vhost_get_avail_idx() if needed. With it,
the caller of the function needn't to worry about memory barriers. Since
we're here, other cleanups are also applied.
Gavin I suggested another approach.
1. Start with the patch I sent (vhost: order avail ring reads after
index updates) just do a diff against latest.
simplify error handling a bit.
2. Do any other cleanups on top.
