Now in sctp_endpoint_init(), it holds the sk then creates auth
shkey. But when the creation fails, it doesn't release the sk,
which causes a sk defcnf leak,
Here to fix it by only holding the sk when auth shkey is created
successfully.
Fixes: a29a5bd4f5c3 ("[SCTP]: Implement SCTP-AUTH initializations.")
