Merge branch 'vhost-fix-vhost_vq_access_ok-log-check'

Stefan Hajnoczi says:

====================
vhost: fix vhost_vq_access_ok() log check

v3:
 * Rebased onto net/master and resolved conflict [DaveM]

v2:
 * Rewrote the conditional to make the vq access check clearer [Linus]
 * Added Patch 2 to make the return type consistent and harder to misuse [Linus]

The first patch fixes the vhost virtqueue access check which was recently
broken.  The second patch replaces the int return type with bool to prevent
future bugs.
