Fix possible double-free during KDB creation

In krb5_dbe_def_encrypt_key_data(), when we free
key_data->key_data_contents[0], reset it to null so the caller doesn't
free it as well.

Since commit a06945b4ec267e8b80e5e8c95edd89930ff12103 this bug
manifests as a double-free during KDB creation if master key
encryption fails.
