Subject: [PATCH] staging: r8188eu: change return type of rtw_set_802_11_disassociate to void

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.
