Daniel Henrique Barboza fae5e343fb dac, selinux: skip setting/restoring label for absent PCI devices
If the underlying PCI device of a hostdev does not exist in the
host (e.g. a SR-IOV VF that was removed while the domain was
running), skip security label handling for it.

This will avoid errors that happens during qemuProcessStop() time,
where a VF that was being used by the domain is not present anymore.
The restore label functions of both DAC and SELinux drivers will
trigger errors in virPCIDeviceNew().
