ath9k: Fix get channel default noise floor

Browse source 
Commit 8da58553cc ("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.
