SCTP: Fixed association parsing error when running "netstat -S" on Fedora

In /proc/net/sctp/assocs on Fedora, in list of local addresses, there is no address
marked as primary by "*". So association parsing failed on line 1054.
With this fix, when no "*" is found, first address is taken as primary
and skipped for printing non-primary addresses.
