The virtio_queue_set_notification() nesting introduced for AioContext polling raised an assertion with virtio-net (even in non-polling mode). Converting virtio-net and virtio-crypto to use virtio_queue_set_notification() in a nesting fashion would be invasive and isn't worth it.
Patch 1 contains the revert to resolve the bug that Doug noticed. Patch 2 is a less efficient but safe alternative.
