PPP, PPPoE, removed unnecessary single pbuf

Browse Source 
Removed ppp_singlebuf() in pppoe_data_input(), chained pbuf are
perfectly acceptable for IP data and we are currently supporting them
perfectly for PPPoS. The PPP stack itself (LCP, IPCP et al.) does not
support chained pbuf and is already calling ppp_singlebuf() just before
passing packet to the protocol handler.
