ath6kl: Remove auth type fall back in auto authentication mode
Target already tries with different authentication mechanism

Brent reported that ath6kl busy loops if firmware doesn't boot for some
reason (in this case he was using an older firmware which wasn't supported

Investigation revealed that this was even on purpose,
ath6kl_bmi_get_rx_lkahd() had a parameter to disable the timeout check,
which is extremely evil. I didn't find any reason why the timeout needs
to be disabled so I just removed the feature. The function already busyloops

fields that the target uses depending on which type of connect

separated from ath6kl_connect_event() so that correct field names

The bug hiding in the previous mess was in parsing the AID incorrectly

When the the Tx BA session is stopped and the HW queues aren't empty,

While in this state, we never wake the SW queue, even when the HW

Once the HW queue is really empty, we must wake the SW queue in order
