LinuxKPI: 802.11: pass internal variable to lkpi_80211_mo_sta_state()

With mac80211 operations (MO) tracing on we have seen some ill-ordered
executions of MO functions. In order to limit visibility of the mac80211
sta, pass the internal version into lkpi_80211_mo_sta_state() and only
there convert to the argument needed. This mostly eases tracing and
debugging.
