pppoe.c: Fix kernel panic caused by __pppoe_xmit
__pppoe_xmit function return value was invalid resulting in
additional call to kfree_skb on already freed skb. This resulted in
memory corruption and consequent kernel panic after PPPoE peer
terminated the link.
This fixes commit 55c95e738da85373965cb03b4f975d0fd559865b.
