iwlwifi: do not clear data after chain noise calib
Chain noise calibration data are cleared after the calibration is done
in iwlagn_gain_computation() and iwl4965_gain_computation(). This cause
the debugfs entries for those data useless. To provide valid debugging
info, clear those data right before starting the calibration instead.
