cfg80211/mac80211: re-add get_channel operation
This essentially reverts commit 2e165b818456 but introduces the get_channel operation with a new wireless_dev argument so that you can retrieve the channel per interface. This is necessary as even though we can track all interface channels (except monitor) we can't track the channel type used. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
