[PATCH v2 net-next] sctp: use sctp_auth_shkey_release() in error path for consistency

Use the proper refcount-aware helper sctp_auth_shkey_release() instead
of kfree() when freeing cur_key in the error path of sctp_auth_set_key().
While both are equivalent in the current code, using the helper maintains
abstraction consistency and prevents potential issues if the code is
reordered in the future.
