[PATCH spice-server 3/3] red-channel: Allows to retrieve client callback saves pointer

[Frediano Ziglio <fziglio@xxxxxxxxxx>]

The data pointer for client callbacks was not used.
The code was saving this information using callback registration
and g_object_set_data. Remove the g_object_set_data using
the data registered.
