Fix libvirtd restart for domains with PCI passthrough devices

When libvirtd shuts down, it places a <state/> tag in the XML
state file it writes out for guests with PCI passthrough
devices.  For devices that are attached at bootup time, the
state tag is empty.  However, at libvirtd startup time, it
ignores anything with a <state/> tag in the XML, effectively
hiding the guest.
This patch remove the check for VIR_DOMAIN_XML_INTERNAL_STATUS
when parsing the XML.
* src/conf/domain_conf.c: remove VIR_DOMAIN_XML_INTERNAL_STATUS
  flag check in virDomainHostdevSubsysPciDefParseXML()
