libnm-core: suppress compiler warning in mac_address_parser()

Browse source 
@buf_len is always initialized when @buf_arr is set but gcc fails to
recognize it:

../libnm-core/nm-keyfile-reader.c: In function 'mac_address_parser':
../libnm-core/nm-keyfile-reader.c:654:36: error: 'buf_len' may be used uninitialized in this function [-Werror=maybe-uninitialized]
  tmp_string = nm_utils_hwaddr_ntoa (buf_arr, buf_len);
