Alfredo Alvarez Fernandez 39e2e173fb locking/lockdep: Print chain_key collision information ...

A sequence of pairs [class_idx -> corresponding chain_key iteration]
is printed for both the current held_lock chain and the cached chain.

That exposes the two different class_idx sequences that led to that
particular hash value.

This helps with debugging hash chain collision reports.
