[spice-server 4/4] worker: Simplify flush_commands()

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

red_disconnect_display() is duplicating what red_channel_disconnect()
already does, so red_disconnect_display() and red_disconnect_cursor()
are actually identical code-wise. We can directly call
red_channel_disconnect() from flush_commands() rather than passing a
'red_disconnect_t disconnect' argument to that function.
