[PATCH for 7.2-rc3 v1 0/2] virtio fixes

[Alex Bennée]

Hi,

This hopefully fixes the problems with VirtIO migration caused by the
previous refactoring of virtio_device_started(). That introduced a
different order of checking which didn't give the VM state primacy but
wasn't noticed as we don't properly exercise VirtIO device migration
and caused issues when dev->started wasn't checked in the core code.
The introduction of virtio_device_should_start() split the overloaded
function up but the broken order still remained. The series finally
fixes that by restoring the original semantics but with the cleaned up
functions.

I've added more documentation to the various structures involved as
well as the functions. There is still some inconsistencies in the
VirtIO code between different devices but I think that can be looked
at over the 8.0 cycle.
