Revert "ath9k: switch to using mac80211 intermediate software queues"

This reverts commit 31e5ed4152c4aa826641b2db6b4245a03dd553b5.
I've noticed some weird powersave related issues with this commit.
Revert until they've been fixed.

-Subject: [PATCH] ath9k: Switch to using mac80211 intermediate software queues.
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This switches ath9k over to using the mac80211 intermediate software
-queueing mechanism for data packets. It removes the queueing inside the
-driver, except for the retry queue, and instead pulls from mac80211 when
-a packet is needed. The retry queue is used to store a packet that was
-pulled but can't be sent immediately.
-
-The old code path in ath_tx_start that would queue packets has been
-removed completely, as has the qlen limit tunables (since there's no
-longer a queue in the driver to limit).
-
-Based on Tim's original patch set, but reworked quite thoroughly.
