vhost: prevent zero copy mode if IOMMU is on

The simultaneous use of dequeue_zero_copy and IOMMU is problematic.
Not only because IOVA_VA mode is not supported but also because the
potential invalidation of guest pages while the buffers are in use,
is not handled.

Prevent these two features to be enabled simultaneously.
