tap: drain queue in tap_send()
Okay, let's try re-enabling the drain-entire-queue behaviour, with a
difference - before each subsequent packet, use qemu_can_send_packet()
to check that we can send it. This is similar to how we check before
polling the tap fd and avoids having to drop a packet if the receiver
cannot handle it.
This patch should be a performance improvement since we no longer have
to go through the mainloop for each packet.
