Dylan Reid 50f2fd369f virtio-devices: block: drain async I/O before pausing ...

During pause the block backend's async I/O path can have unfinished I/O
requests. A snapshot or migration RAM copy taken after pause returns can
then race with kernel writes and capture torn pages.

Since vCPUs are already paused, the VMM thread can stop new block
submissions and wait for the worker to drain before parking the worker
threads.
