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") Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Karl Beldan <karl.beldan@rivierawaves.com> Cc: Eric Dumazet <edumazet@google.com> Cc: David S.
