VF FLR requires additional processing done by PF driver. The processing is done after FLR is already finished from PCIe perspective. In order to avoid a scenario where migration state transitions while PF processing is still in progress, additional synchronization point is needed. Add a helper that will be used as part of VF driver struct pci_error_handlers .reset_done() callback.
