lib/checksum.c: fix build for generic csum_tcpudp_nofold
Fixed commit added from64to32 under _#ifndef do_csum_ but used it
under _#ifndef csum_tcpudp_nofold_, breaking some builds (Fengguang's
robot reported TILEGX's). Move from64to32 under the latter.
Fixes: 150ae0e94634 ("lib/checksum.c: fix carry in csum_tcpudp_nofold")
