Prevent sending stream close frames back to the sender

The OnDvLastFramePacketIn() function closed the current stream before
HandleQueue() was called, so the stream's client lost it's stream master status
and HandleQueue() sent the client's last (stream closing) frame back to the
sender.

Applying this commit closes the stream only after HandleQueue() has been
called so no unnecessary call end frame reflection happens to the transmitting
client.
