[spice-gtk 1/2] spice_channel_coroutine: emit signals in all error cases

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

There are several very unlikely failures where no signal is emitted
to indicate the failure. Since applications rely on these signals
to detect spice-gtk connection failures, it's important to emit
one in all error cases.
