The peripheral controller driver is getting a USB reset interrupt. Should it then be calling the gadget driver's disconnect function, i.e. gadgetfs_disconnect, which will pass the disconnect up to the application layer? The controller driver should call the disconnect routine when the host is powered off, but not all devices are capable of detecting this. Have you tried testing with a different gadget driver, such as g_zero or g_file_storage?
