OSSL_STORE and PKCS#12: Check if there is a MAC to verify before prompting
When a DER object with unknown contents comes all the way to
ossl_store_handle_load_result(), and it attempts to decode them as different
objects, the PKCS#12 decoding attempt would (almost) always prompt for a
passphrase, even if there isn't a MAC to verify it against in the PKCS#12
object.
This change checks if there is a MAC to verify against before attempting to
prompt for a passphrase, leading to less surprising behavior.
