[PATCH v3 06/14] domain_conf: move vendor, product and tray checks to domain_validate.c

[Daniel Henrique Barboza <danielhb413@xxxxxxxxx>]

The 'tray' check isn't a XML parse specific code and can be pushed
to the validate callback, in virDomainDiskDefValidate().

'vendor' and 'product' string sizes are already checked by the
domaincommon.rng schema, but can be of use in the validate callback
since not all scenarios will go through the XML parsing.
