device: Return error when ConnectProfile DBus method fails

Without this patch ConnectProfile DBus method does not return failure if profile connection failed and some other profile was already connected. This is not correct behavior as ConnectProfile DBus method should always return error when specified profile failed to connect. This patch fixes this it.
