wext: Fix deauthentication to do IW_MLME_DEAUTH prior to disconnect

4853d5ac847efbfe54b80eeefabc2932696414c9 had a small bug in the order
of these function calls in _wext_deauthenticate() (_disassociate()
did have the correct order). The deauthentication frame is supposed
to go out (if driver supports that) before we disconnect more
forcefully.
