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.
