PCI: Check IORESOURCE_UNSET before updating BAR Check to make sure we don't update a BAR with an address we haven't assigned. If we haven't assigned an address to a resource, we shouldn't write it to a BAR. This isn't a problem for the usual path via pci_assign_resource(), which clears IORESOURCE_UNSET before calling pci_update_resource(), but paths like pci_restore_bars() can call this for resources we haven't assigned.
