Marco Varlese 04e5d64c45 SCTP: fix connection memory corruption
A bug was found when multiple SCTP connections were being opened to the
same SCTP server. This patch addresses that problem, removing the use of
the 'parent' pointer approach for sub-connection and saving instead
within the sub-connection itself the ID representing its position. That
facilitates pointer-arithmetic to be computed in the
get_connection_from_transport().
