Fam Zheng 1ef4a6069f stellaris_enet: Flush queued packets when read done 
If s->np reaches 31, the queue will be disabled by peer when it sees
stellaris_enet_can_receive() returns false, until we explicitly flushes
it which notifies the peer. Do this when guest is done reading all
existing data.

Move the semantics to stellaris_enet_receive, by returning 0 when the
buffer is full, so that new packets will be queued.  In
stellaris_enet_read, flush and restart the queue when guest has done
reading.
