syncppp: Fix crashes.

The syncppp layer wants a mid-level netdev private pointer.

It was using netdev->priv but that only worked by accident,
and thus this scheme was broken when the device private
allocation strategy changed.

Add a proper mid-layer private pointer for uses like this,
update syncppp and all users, and remove the HDLC_PPP broken
tag from drivers/net/wan/Kconfig

           Generic HDLC driver supporting PPP over WAN connections.
-          This module is currently broken and will cause a kernel panic
-          when a device configured in PPP mode is activated.
 
           It will be replaced by new PPP implementation in Linux 2.6.26.
