BACKPORT: locking/lockdep: Remove unused @nested argument from lock_release()

Browse Source 
Since the following commit:

  b4adfe8e05f1 ("locking/lockdep: Remove unused argument in __lock_release")

@nested is no longer used in lock_release(), so remove it from all
lock_release() calls and friends.
