Fixed java.lang.NullPointerException

From @AntTheAlchemist:
This is an interesting one, on a Xiaomi MiTV. Caused by a camera device, full stack:
android.app.LoadedApk$ReceiverDispatcher$Args.lambda$getRunnable$0$LoadedApk$ReceiverDispatcher$Args -> org.libsdl.app.HIDDeviceManager$1.onReceive -> handleUsbDeviceAttached -> connectHIDDeviceUSB -> getSerialNumber -> android.hardware.usb.UsbDevice.getSerialNumber -> android.hardware.usb.IUsbSerialReader$Stub.onTransact -> com.android.server.usb.UsbSerialReader.getSerial -> UsbUserPermissionManager.checkPermission -> hasPermission -> isCameraDevicePresent
