Nicolai Stange 9561475db6 PCI: Fix race condition with driver_override
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 6265539776 ("driver core: platform:
fix race condition with driver_override") from Adrian Salido.

Fixes: 782a985d7a ("PCI: Introduce new device binding path using pci_dev.driver_override")
