Markus Armbruster cfa9bb2369 qmp hmp: Improve error messages when SPICE is not in use
Commit 7572150 adopted QERR_DEVICE_NOT_ACTIVE for the purpose,
probably because adding another error seemed cumbersome overkill.
Produces "No spice device has been activated", which is awkward.

We've since abandoned our quest for "rich" error objects.  Time to
undo the damage to this error message.  Replace it by "SPICE is not in
use".

Keep the stupid DeviceNotActive ErrorClass for compatibility, even
though Libvirt doesn't use it.
