mac80211: aggregation: Convert timers to use timer_setup()

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

This removes the tid mapping array and expands the tid structures to
add a pointer back to the station, along with the tid index itself.

[switch tid variables to u8, the valid range is 0-15 at most,
 initialize tid_tx->sta/tid properly]
