driver core: platform: fix race condition with driver_override
commit 6265539776a0810b7ce6398c27866ddb9c6bd154 upstream.
The driver_override implementation is susceptible to race condition when
different threads are reading vs storing a different driver override.
Add locking to avoid race condition.
