Change return type of rtw_set_802_11_disassociate to void. This function
always returns 'true' no matter what, so there is no need to return a
value, and no need to check for it in the two call sites within
rtw_wx_set_mlme. Also, as we are no longer using ret in rtw_wx_set_mlme
except as the return value, just remove it and return 0 directly.

Suggested-by: Michael Straube <straube.linux@gmail.com>
Signed-off-by: Phillip Potter <phil@philpotter.co.uk>
---

Changes from V1: Act on feedback from Michael Straube:
* Remove ret variable from rtw_wx_set_mlme and return 0 directly in
  success case.
