ath9k: Fix the 'xmit' debugfs file
The 'xmit' debugfs file has become big and unwieldy, fix
multiple issues with its usage:
* Store TX counters/statistics only for the 4 Access Categories.
Use IEEE80211_NUM_ACS instead of ATH9K_NUM_TX_QUEUES.
* Move various utility macros to debug.h, they can be reused
elsewhere.
* Remove tx_complete_poll_work_seen.
* Remove code that accesses various internal queue-specific
variables without any locking whatsoever. HW/SW queue details
will be handled in a subsequent patch.
* Do not print internal values like txq_headidx and txq_headidx.
They were mostly unused anyway, considering code like:
PRX("txq_tailidx: ", txq_headidx);
* Handle 'txprocdesc' for EDMA too.
