domain_conf: move virDomainDiskDefValidate() to domain_validate.c
Next patch will add more validations to the function. Let's move it beforehand to domain_validate.c. virSecurityDeviceLabelDefValidateXML() is still used inside domain_conf.c, so make it public for now until its current caller (virDomainChrSourceDefValidate()) is also moved to domain_validate.c.
