net/sched: act_csum: don't mangle UDP tunnel GSO packets
Similar to commit add641e7dee3 ("sched: act_csum: don't mangle TCP and
UDP GSO packets"), UDP tunnel GSO packets going through act_csum
shouldn't have their checksum calculated at this point, because it will
be done after segmentation. Setting the checksum in act_csum modifies
skb->ip_summed and prevents inner IP csum offload from kicking in,
resulting in a packet with a bad checksum.
Add UDP tunnel GSO packets to the exceptions, and also add UDP GSO
(SKB_GSO_UDP_L4), as the same logic as in the commit mentioned above
applies to UDP GSO too.
