We've had cases (especially with vhost) in the past where we have
a valid vaddr but the backing page was not assigned yet. DPDK used
to return 0 as the phys addr in these cases but now it returns
RTE_BAD_IOVA. Unfortunately we don't have any tests currently
in the test pool that hit this condition, but at least one user
has an environment which hits it and this patch fixes their
problem.
Make sure we still work with older versions of DPDK as well.
Fixes issue #260.
