SCTP: Fix to handle invalid parameter length correctly
If an INIT with invalid parameter length look like this:
Parameter Type : 1
Parameter Length: 800
and not contain any payload, SCTP will ignore this parameter and send
back a INIT-ACK.
This patch is fix to handle this invalid parameter length correctly.
