[PATCH] media: as102: drop device reference on probe failure

[Jiawen Liu]

as102_usb_probe() initializes the kref and takes a USB device
reference before registering the USB minor.

If stream allocation or DVB registration fails later, the error
path deregisters the minor but does not drop the initial kref.

Use kref_put() so as102_usb_release() drops the USB reference.
