net80211: fix scanning after D5145 (PR 197498 related)

- In case, when we are doing <smth> -> INIT (FEXT_REINIT) -> <smth2>
state transition, cancel_scan() may be called in the first transition.
Reenqueue second state transition, so things will be executed in order.
- Discard any AUTH+ state transition request when INIT -> SCAN
transition is not done.
- Allow to track discarded state transitions via 'state' debugging
category.

Tested with:
 * RTL8188EU, HOSTAP mode.
 * RTL8188CUS, STA mode.
 * Intel 3945BG, IBSS and STA modes.
