virtio: document queue state logic
commit d631b94e7a15277858ec5f88d674d93080506999
virtio: change comment in transmit
started clarifying the logic behind queue state management,
but introduced an inaccuracy: TX_BUSY does not cause
a BUG message.
Clean this up some more, explaining the tradeoffs in detail.
