Subject: [PATCH] src/qemu/qemu_domain.c: Fix overriding audioBackend in
 qemuDomainDefSuggestDefaultAudioBackend

If we have Spice and VNC graphics in domain XML, and Spice graphics defined before VNC, audioBackend will be overrided in qemuDomainDefSuggestDefaultAudioBackend to VIR_DOMAIN_AUDIO_TYPE_NONE, and we will have no sound in Spice session, like this https://bugs.launchpad.net/qemu/+bug/1900352. If the flag addAudio already set, we do not need to override audioBackend. This commit fix the issue.
