conf: Move virDomainCheckVirtioOptions() into domain_validate.c

Browse Source 
The aim of virDomainCheckVirtioOptions() function is to check
whether no virtio options are set, i.e. no @iommu no @ats and no
@packed attributes were present in given device's XML (yeah, the
function has very misleading name). Nevertheless, this kind of
check belongs to validation phase, but now is done in post parse
phase. Move the function and its calls to domain_validate.c so
that future code is not tempted to repeat this mistake.
