iwlwifi: do not call ieee80211_frequency_to_channel
A few cases in iwlwifi driver function ieee80211_frequency_to_channel()
is called to get channel number from center frequency. This is not needed
since the channel number is already saved in hw_value field of struct
ieee80211_channel in function iwlcore_init_geos(). So replace those function
calls with hw_value field of struct ieee80211_channel.
