    nshlib/fscmds:Fix write overflow during cp -r process
    
    Summary:
          do
            {
              nbyteswritten = write(wrfd, iobuffer, nbytesread);
              if (nbyteswritten >= 0)
    
    The write return type is ssize_t, which is different in size from the 
originally declared type, so the unified type is ssize_t
