mac80211: clean up/fix aggregation code
The aggregation code has a number of quirks, like inventing an unneeded WLAN_BACK_TIMER value and leaking memory under certain circumstances during station destruction. Fix these issues by using the regular aggregation session teardown code and blocking new aggregation sessions, all before the station is really destructed. As a side effect, this gets rid of the long code block to destroy aggregation safely. Additionally, rename tid_state_rx which can only have the values IDLE and OPERATIONAL to tid_active_rx to make it easier to understand that there is no bitwise stuff going on on the RX side -- the TX side remains because it needs to keep track of the driver and peer states.
