sctp: shrink sctp_tsnmap some more by removing gabs array
The gabs array in the sctp_tsnmap structure is only used in one place, sctp_make_sack(). As such, carrying the array around in the sctp_tsnmap and thus directly in the sctp_association is rather pointless since most of the time it's just taking up space. Now, let sctp_make_sack create and populate it and then throw it away when it's done. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
