Noise floor calibration is performed on longcal interval and the reading will be updated in history buffer. On rare occasions, the previous noisefloor calibration might not be completed within the period and trying to load nf reading will be failed. In such situation, postpone the nf cabliration to next cycle to give enough time to complete the calibration. This was already taken care for ar9002 chips.
