Subject: [PATCH] ath9k: Fix get channel default noise floor
Git-commit: b9607de6cf22a5cd268b9206177a9baafb6e8ac8
Patch-mainline: v4.16-rc1
References: FATE#326906
Commit 8da58553cc63 ("ath9k: Use calibrated noise floor value
when available") introduced regression in ath9k_hw_getchan_noise
where per chain nominal noise floor has been taken instead default
for channel.
Revert to original default channel noise floor.
Fixes: 8da58553cc63 ("ath9k: Use calibrated noise floor value when available")
