net: disable receiving if client returns zero

If a receiver returns zero, that means its queue is full and it will
notify us when room is available using qemu_flush_queued_packets().

Take note of that and disable that receiver until it flushes its queue.

This is a first step towards allowing can_receive() handlers to return
true even if no buffer space is available.
