driver core: Add missing annotation for device_links_write_lock()



Sparse reports a warning at device_links_write_lock()

warning: context imbalance in evice_links_write_lock()
	 - wrong count at exit

The root cause is the missing annotation at device_links_write_lock()
Add the missing __acquires(&device_links_srcu) annotation
