PCI: Fix race condition with driver_override
commit 9561475db680f7144d2223a409dd3d7e322aca03 upstream.
The driver_override implementation is susceptible to a race condition when
different threads are reading vs. storing a different driver override. Add
locking to avoid the race condition.
This is in close analogy to commit 6265539776a0 ("driver core: platform:
fix race condition with driver_override") from Adrian Salido.
Fixes: 782a985d7af2 ("PCI: Introduce new device binding path using pci_dev.driver_override")
