Whenever a device is being updated via
virDomainUpdateDeviceFlags() API, we parse the device XML and
ideally run some generic checks to validate the configuration
(e.g. if device defines per-device boot order but the domain has
os/boot element already). Well, that's the theory - due to a
missing check we've jumped early from that check function.

^Which means that now the 'compatibility' check is only skipped for _DETACH
(which, for _DETACH, has been the case since @1c13166134). Therefore I think
that codewise, even though you're change makes sense, it would be IMHO nicer to
just drop this condition all together and also drop the call to this validation
helper from the *Detach helper (with the appropriate tuning of the validator's
signature of course).
With that adjustment:
