pci: Remove unused restore() implementations

Browse Source 
Now that VirtioPciDevice, VfioPciDevice and VfioUserPciDevice have all
been moved to the new restore design, there's no need to keep the old
way around, therefore the restore() implementations for MsiConfig,
MsixConfig and PciConfiguration can be removed.
