Following removal of _rtl92e_ioctl this function along with associated
macros, structure ieee_param and functions become dead code.
Remove functions rtllib_wpa_enable, rtllib_wpa_assoc_frame, rtllib_wpa_mlme,
rtllib_wpa_set_wpa_ie, rtllib_wpa_set_auth_algs, rtllib_wpa_set_param,
rtllib_wpa_set_encryption and rtllib_wpa_supplicant_ioctl.
