udp: Support BIG TCP GSO packets where they can occur

Wherever a GSO packet can occur, and its length is used to fill the UDP
header, use udp_set_len that assigns 0 if the length doesn't fit 16
bits, so that the packet can be properly parsed and segmented later,
instead of having truncated length.

Use udp_get_len in udp_validate_len to treat BIG TCP packets as valid.
