[DCCP]: Use AF-independent rebuild_header routine



This fixes a nasty bug: dccp_send_reset() is called by both DCCPv4 and DCCPv6, but uses
inet_sk_rebuild_header() in each case. This leads to unpredictable and weird behaviour:
under some conditions, DCCPv6 Resets were sent, in other not.

The fix is to use the AF-independent rebuild_header routine.
