svn commit: r299105 - stable/9/sys/compat/ndis

Log:
  MFC r298731, r298734:
  ndis(4): unsign some indexes to prevent overflows.
  
  The "len" parameter is uint32_t, indexing it with an int may
  end up in a signed integer overflow.
  
  strlen(3) returns an integer of size_t but a correponding index
  of type u_int is more than enough.
