[PATCH 16/21] domain_conf.c: move virDomainPCIControllerOpts checks to post parse

[Daniel Henrique Barboza <danielhb413@xxxxxxxxx>]

virDomainControllerDefParseXML() does a lot of checks with
virDomainPCIControllerOpts parameters that can be moved to
post parse time, sharing the logic with other use cases that
does not rely on XML parsing.
