sctp: change to hold sk after auth shkey is created successfully
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.
