    LinuxKPI 802.11 / rtw88: make packets flow again

    In 886653492945f we added checks for packets to only go out if the
    station is known to the firmware (amongst others) as there are
    implications in drivers.
    Unfortunately rtw88 does not support the mac80211 (*sta_state)() KPI
    but only the fallback (*sta_add/remove)() in which case the station is
    only added to firmware when going from AUTH to ASSOC.  That means we
    had no chance to get authenticated anymore.

    The problem has existed since June in main and stable/14 but only now
    was noticed in December with 14.2-R which makes me wonder.

    I am still not entirely sure what implications the missing checks have
    on all the other drivers using (*sta_state)() (or if they were really
    needed in first place beyond txq_ready) but I have run a few days of
    iwlwifi with this without extra trouble but I was not always able to
    reproduce problems in the past.  Also people are occasionally still
    reporting the original "Invalid TXQ" error which indicates there is
    another lingering case somewhere.

    For the moment make rtw88 work again and expose the change to a wider
    audience.

    Fixes:  886653492945f (make sure we can send DISASSOC or DEAUTH frames)
