We get report [1] that CPU is running in hot loop while requesting firmware stats,
fix it in patch [1/6]. While at it, fix potential failures due to static variables
in patch [2/6]. patch [3/6] fix potential issues in cases ath11k debugfs is not
enabled. patch [4/6] fix lock symmetry issue. and the last two patches refactor
firmware stats request helpers such that we can remove some redundant code.

[1] https://lore.kernel.org/all/7324ac7a-8b7a-42a5-aa19-de52138ff638@app.fastmail.com

v2:
 - rebased on ToT
 - use completion mechanism in patch "wifi: ath11k: avoid burning CPU in
   ath11k_debugfs_fw_stats_request()"
 - add new patch: "wifi: ath11k: don't wait when there is no vdev started"
 - update copyright where applicable
