nshlib/fscmds:Fix write overflow during cp -r process

Browse Source 
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
