[PATCH spice-server 03/10] reds-stream: Remove shutdown field

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

This field was used only by RedChannelClient to mark when the
socket was shutdown. This condition can simply be tested by
RedChannelClient checking if there's a watch as is the only
condition (beside object destroying) where the watch is removed.
In any case the shutdown was used to understand if there were
possible data still to read.
