Xin Long 92598c5db1 sctp: change to hold sk after auth shkey is created successfully ...

[ Upstream commit 25bff6d547 ]

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.
