driver core: Add conditional guard support for device_trylock()
Introduce a conditional guard version of device_trylock() for scenarios
that must not block on the device lock. device_trylock() returns 1 on
success like mutex_trylock(), so the default binary condition applies and
ACQUIRE_ERR() reports -EBUSY on contention.
