net: pppoe: use correct channel MTU when using Multilink PPP

Hello,

when computing the PPPoE channel MTU, we have to subtract two bytes, as ppp_mp_explode() expects the channel MTU to exclude the size of the PPP protocol field, which is correct according to RFC 1661.

See patch 1 for details.

Best regards,

Christoph
