[PATCH] driver core: fix inverted "locked" suffix of driver_match_device()

[Danilo Krummrich <dakr@kernel.org>]

In the current implementation driver_match_device() expects the device
lock to be held, while driver_match_device_locked() acquires the device
lock.

By convention it should be the other way around, hence swap the name of
both functions.

Fixes: dc23806a7c47 ("driver core: enforce device_lock for driver_match_device()")
