[PULL] vhost/virtio/qemu: cleanups and fixes

[Michael S. Tsirkin]

DMA support in FW CFG had to be pushed out as it caused ltp failures -
likely a compatibility issue, and could be a hypervisor bug, but we need
to figure it out first. There's still a small chance it'll happen
shortly, then I might do another pull request just for that.
