[NETFILTER]: PPTP conntrack: fix another GRE keymap leak
When the master PPTP connection times out while still having unfullfilled expectations (and a GRE keymap entry) associated with it, the keymap entry is not destroyed. Add a destroy callback to struct ip_conntrack_helper and use it to destroy PPTP siblings when the master is destroyed. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
