KVM: Use pci_store/load_saved_state() around VM device usage
Store the device saved state so that we can reload the device back
to the original state when it's unassigned. This has the benefit
that the state survives across pci_reset_function() calls via
the PCI sysfs reset interface while the VM is using the device.
