Interworking: Fix already-connected check to verify network priority
Commit d28f4e44f10a8549d969e5434f7d4d16f462dfcc optimized Interworking network selection in a case where the operation is run while already connected to the selected network by skipping the reconnection. However, this did not take into account that a higher priority network may have shown up in the new scan results. Fix this by checking whether network selection based on the latest scan results (the ones from the interworking_select operation) would result in a network with higher priority being selected. If so, skip the optimization and force normal network connection (which will select this newly found higher priority network). This fixes cases where a non-Hotspot 2.0 network with higher priority (e.g., home network) shows up while connected to a Hotspot 2.0 network with lower priority.
