[PULL 10/12] audio/spiceaudio: Fail initialisation when not using spice

[Paolo Bonzini]

From: Martin Kletzander <mkletzan@redhat.com>

The caller would already fail, but this way the message can better
express the reason for the failure.

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=2043498
