socket: mark skbs as not on list when receiving via gro
Certain drivers will pass gro skbs to udp, at which point the udp driver simply iterates through them and passes them off to encap_rcv, which is where we pick up. At the moment, we're not attempting to coalesce these into bundles, but we also don't want to wind up having cascaded lists of skbs treated separately. The right behavior here, then, is to just mark each incoming one as not on a list. This can be seen in practice, for example, with Qualcomm's rmnet_perf driver. Signed-off-by: Jason A.
