ip_tunnel: Do not use mark in skb by default

Browse source

This reverts commit 5c38bd1b82.

skb->mark contains the mark the encapsulated traffic which
can result in incorrect routing decisions being made such
as routing loops if the route chosen is via tunnel itself.
The correct method should be to use tunnel->fwmark.
