iwlwifi: mvm: responder: allow to set only the HLTK for an associated station

Browse Source 
For secure ranging with an associated station, the driver only needs
to set the HLTK. There is no need to add an internal station for PMF
since the FW will use the existing station which already has the TK
installed.
