  Add another fix to the 1's complement checksum.  A second carry does not
  occur when the individual packet csum's are set to 0xffff, which is normally
  the case.  But if we ever use csum_data to accumulate partial fragment
  checksums then a second carry can occur which must be handled.  Fix it now.
