From: Mohammed Shafi Shajakhan <mshajakhan@xxxxxxxxxxx>
In the ath9k debugging feature 'wiphy' the current channel used by the
station is incorrectly displayed.This is because the channels available
are sequentially mapped from numbers 0 to 37.This mapping cannot be
changed as the channel number is also used as an array index
This fix solves the above problem by calculating the channel
number from center frequency.
