PPP, PPPoL2TP, merged pppol2tp_input_ip() to pppol2tp_input()

Browse Source 
We don't need anymore an input function for ip4 and an input function
for ip6, work to achieve that was partially done by ce7e31cd.
pppol2tp_input() is now only called by pppol2tp_input_ip(), finishing
dual stack support by merging pppol2tp_input_ip() into pppol2tp_input().
