Heap corruption in ipapwd plugin
ipapwd_encrypt_encode_key allocates 'kset' on the heap but
with num_keys and keys not being initialized.
Then ipa_krb5_generate_key_data initializes them with the
generated keys.
If ipa_krb5_generate_key_data fails (here EINVAL meaning no
principal->realm.data), num_keys and keys are left uninitialized.
Upon failure, ipapwd_keyset_free is called to free 'kset'
that contains random num_keys and keys.
allocates kset with calloc so that kset->num_keys==0 and
kset->keys==NULL
