Subject: [PATCH] qemu: Remove unused params from qemuDomainDeviceDefValidate

Neither @cfg nor (now) @driver is used in the API, so remove them
and mark @opaque as UNUSED.

NB: Commit id 'fa3c558596' dropped the unused @qemuCaps which was the
last consumer of @driver other than @cfg, but even @cfg was never used
even in the original implementation from commit id 'd987f63a'.
