When qemu only accepts TLS connections, but spice-gtk is given an URI with
both port and tls-port specified, spice_session_channel_open_host() is
first attempted to the non-TLS port, and when that fails,
spice_channel_coroutine() retries a TLS connection.
Commit 3edcc04 broke this as when the non-TLS connection fails, an error is
set, and the TLS fallback is no longer attempted.
This commit fixes this by not reporting an error when we are attempting a
non-TLS connection, a TLS port is specified, and the non-TLS connection
failed with G_IO_ERROR_CONNECTION_REFUSED.
