DPDK by default guesses that it should be using iova-mode=va
so that it can support running as an unprivileged user. However,
some systems (especially virtual machines) don't have an IOMMU capable
of handling the full virtual address space and DPDK doesn't
currently catch that. Add a check in SPDK and force iova-mode=pa
here.
