LinuxKPI: 802.11: make sure we are scheduled before wake_tx_queue()

If we are not scheduled before calling wake_tx_queue() packets may
never go out, which at first will look like EAPOL fails (as
wpa_supplicant suggest possibly with a wrong key).  Using monitor
mode it will be clear what is going on.
Pass a flag down to wake_tx_queue() to call ieee80211_schedule_txq()
in case (*wake_tx_queue)() is supported or not, which solves the
problem for the lkpi_80211_txq_tx_one() which was failing.
