ath9k: load noise floor from history after the full chip reset
Currently during the full reset, the nf calibration is always restarted from the defaults. The noise floor history buffers are never be used again after the scan and ath reset. This patch ensures that nf histories are always be used that helps to improve the signal quality on congested environment Signed-off-by: Rajkumar Manoharan <rmanohar@qca.qualcomm.com> Signed-off-by: John W.
