pxrc_probe() calls usb_get_dev(), but there is no usb_put_dev()
anywhere in the driver.

The patch adds one to error handling code and to pxrc_disconnect().

Found by Linux Driver Verification project (linuxtesting.org).

Hmm, the biggest question however if we need to "take" the device, as I
do not think interface can outlive the device, and whether we actually
need to store it in pxrc, as we only need it during set up, as far as I
can see.

Thanks.
