Subject: [PATCH 2/5] pem_CreateObject: fix memory leak in the cert search loop

If we search the array in reverse direction and stop on the first match,
we end up with the same results but without leaking certDER.data in each
iteration after the first match.

Subject: [PATCH 3/5] pem_CreateObject: check object ID in the cert search loop

We need to find a certificate that refers to the key being added,
which is not necessarily the last certificate added to the slot.
