net: fix usbnet_receive() packet drops
The USB network interface has a single buffer which the guest reads
from. This patch prevents multiple calls to usbnet_receive() from
clobbering the input buffer. Instead we queue packets until buffer
space becomes available again.
This is inspired by virtio-net and e1000 rxbuf handling.
