Follow the rules for the vhost-user protocol to enable and disable processing. Particularly, avoid processing DMA requests when the guest driver is offline because they will contain garbage.
This fix should resolve all QEMU-related failures in the test matrix for the l2fwd benchmark. Compare new results and old results. Highlights that there are still a couple of DPDK-related interop problems to resolve afterwards.
