udp: fix receiving fraglist GSO packets

commit b128ed5ab27330deeeaf51ea8bb69f1442a96f7f upstream.

When assembling fraglist GSO packets, udp4_gro_complete does not set
skb->csum_start, which makes the extra validation in __udp_gso_segment fail.

BUG=b/365630179
TEST=presubmit
RELEASE_NOTE=None

Fixes: 89add40066f9 ("net: drop bad gso csum_start and offset in virtio_net_hdr")
