Martin KaFai Lau 79c6a8c099 bpf: udp: Avoid calling reuseport's bpf_prog from udp_gro
commit 257a525fe2 upstream.

When the commit a6024562ff ("udp: Add GRO functions to UDP socket")
added udp[46]_lib_lookup_skb to the udp_gro code path, it broke
the reuseport_select_sock() assumption that skb->data is pointing
to the transport header.

This patch follows an earlier __udp6_lib_err() fix by
passing a NULL skb to avoid calling the reuseport's bpf_prog.

Fixes: a6024562ff ("udp: Add GRO functions to UDP socket")
