[PATCH spice-server v2 4/7] red-client: Make sure MainChannelClient is freed as last

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

MainChannelClient is used by other clients to store some data
so should not disappear if other clients are still present.
Keep a owning reference to it and release after RedClient is
released.
