PCI: Return NULL for to_pci_driver(NULL)
to_pci_driver() takes a pointer to a struct device_driver and uses
container_of() to find the struct pci_driver that contains it.
If given a NULL pointer to a struct device_driver, return a NULL pci_driver
pointer instead of applying container_of() to NULL.
This simplifies callers that would otherwise have to check for a NULL
pointer first.
