Might want to hold off on that.

Its been reported by testing that wcn36xx_smd_delete_sta_context_ind() 
actually _is_ firing.

But if you look at wcn36xx_smd_delete_sta_context_ind() it doesn't seem 
to do ieee80211_connection_loss() like it presumably should.

I think the right fix here might be to call ieee80211_connection_loss() 
in wcn36xx_smd_delete_sta_context_ind() if (wcn->hw & CONNECTION_MONITOR)
