Konrad Rzeszutek Wilk 7d66a4ba69 libvchan: Read prod/cons only once. ...

We must ensure that the prod/cons are only read once and that
the compiler won't try to optimize the reads. That is split
the read of these in multiple instructions influencing later
branch code. As such insert barriers when fetching the cons
and prod index.

This is part of XSA155.
