The isc_nm_*connect() functions were refactored to always return the connection status via the connect callback instead of sometimes returning the hard failure directly (for example, when the socket could not be created, or when the network manager was shutting down). This commit changes the connect functions in all the network manager modules, and also makes the necessary refactoring changes in places where the connect functions are called.
