[PULL] vhost: cleanups and fixes

[Michael S. Tsirkin]

These changes were as in linux-next as e1c287efcd4cf688564ed1112d032b5dac29b159 -
I tweaked the commit log slightly.

Too many people were complaining of warnings and errors in virtio
so I decided revert is the safest path forward right now.

The following changes since commit a71c9a1c779f2499fb2afc0553e543f18aff6edf:

  virtio-pci: Remove affinity hint before freeing the interrupt (2017-04-11 00:30:20 +0300)

----------------------------------------------------------------
virtio: oops fixes

virtio pci rework using shared interrupts caused a lot of issues. We
tried to fix them but run out of time. Revert for now, and revisit the
issue for the next kernel.

Luckily we are able to do this without loosing automatic
interrupt NUMA affinity which was the main motivator for the
rework.
