Subject: Error out when tls-channel option is used without TLS
X-Git-Tag: TizenStudio_2.0_p2.3.2~208^2~4430^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=35c633291439185d3bbf84da23db1572498e0d5d;p=sdk%2Femulator%2Fqemu.git

Error out when tls-channel option is used without TLS

It's currently possible to setup spice channels using TLS when
no TLS port has been specified (ie TLS is disabled). This cannot
work, so better to error out in such a situation.
