lockdep: Assign lock keys on registration
Lockdep is assigning lock keys when a lock was looked up. This is
unnecessary; if the lock has never been registered then it is known that it
is not locked. It also complicates the calling convention. Switch to
assigning the lock key in register_lock_class().
