staging: wfx: drop unicode characters from strings

Smatch complains:

  hif_rx.c:235 hif_generic_indication() warn: format string contains non-ascii character '\xc2'
  hif_rx.c:235 hif_generic_indication() warn: format string contains non-ascii character '\xb0'
   234                  if (!wfx_api_older_than(wdev, 1, 4))
   235                          dev_info(wdev->dev, "Rx test ongoing. Temperature: %d°C\n",
                                                                                     ^
   236                                   body->data.rx_stats.current_temp);

So, replace the unicode character.
