netdev: fix RoamThreshold5G
The RoamThreshold5G was never honored because it was being set prior to any connections. This caused the logic inside netdev_cqm_rssi_update to always choose the 2GHz threshold (RoamThreshold) due to netdev->frequency being zero at this time. Instead call netdev_cqm_rssi_update in all connect/transition calls after netdev->frequency is updated. This will allow both the 2G and 5G thresholds to be used depending on what frequency the new BSS is. The call to netdev_cqm_rssi_update in netdev_setup_interface was also removed since it serves no purpose, at least now that there are two thresholds to consider.
