conf: delete unused flags arguments

For static functions not used as callbacks, there's no need to
keep an unused parameter.

* src/conf/domain_conf.c (virDomainChrDefParseTargetXML)
(virDomainTimerDefParseXML, virDomainHostdevSubsysUsbDefParseXML)
(virDomainVcpuPinDefParseXML): Drop unused parameter.
(virDomainChrDefParseXML, virDomainDefParseXML)
(virDomainHostdevDefParseXML): Update callers.
(virDomainNetDefParseXML): Mark flags used.
