Wei Yongjun a869981423 [SCTP]: Fix kernel panic while received ASCONF chunk with bad serial number 
While recevied ASCONF chunk with serial number less then needed, kernel
will treat this chunk as a retransmitted ASCONF chunk and find cached
ASCONF-ACK chunk used sctp_assoc_lookup_asconf_ack(). But this function
will always return NO-NULL. So response with cached ASCONF-ACKs chunk
will cause kernel panic.
In function sctp_assoc_lookup_asconf_ack(), if the cached ASCONF-ACKs
list asconf_ack_list is empty, or if the serial being requested does not
exists, the function as it currectly stands returns the actuall
list_head asoc->asconf_ack_list, this is not a cache ASCONF-ACK chunk
but a bogus pointer.
