[spice-server 3/4] cursor: Remove cursor_channel_disconnect()

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

cursor_channel_disconnect() calls
cursor_channel_client_reset_cursor_cache() on all CursorChannelClient
associated with the current CursorChannel before calling
red_channel_disconnect().

red_channel_disconnect() will iterate over all CursorChannelClient
calling red_channel_client_disconnect(), which will eventually call
CursorChannelClient::on_disconnect. This will in turn
cursor_channel_client_reset_cursor_cache(), so calling it in
cursor_channel_disconnect() before calling red_channel_disconnect() is
redundant.

cursor_channel_disconnect() can thus be replaced by a direct call to
red_channel_disconnect().
