locking/lockdep: Fix reported required memory size (2/2)

Lock chains are only tracked with CONFIG_PROVE_LOCKING=y. Do not report
the memory required for the lock chain array if CONFIG_PROVE_LOCKING=n.
See also commit:

  ca58abcb ("lockdep: sanitise CONFIG_PROVE_LOCKING")

Include the size of the chain_hlocks[] array.
