[SCTP]: Fix protocol violation when receiving an error lenght INIT-ACK
When receiving an error length INIT-ACK during COOKIE-WAIT, a 0-vtag ABORT will be responsed. This action violates the protocol apparently. This patch achieves the following things. 1 If the INIT-ACK contains all the fixed parameters, use init-tag recorded from INIT-ACK as vtag. 2 If the INIT-ACK doesn't contain all the fixed parameters, just reflect its vtag.
