Issue of the Implementation # L0167

Brief

at76c50x-usb: use after free on failure path in at76_probe()

Detailed Description

After commit 174beab7d445 ("at76c50x-usb: Don't perform DMA from stack memory") at76_delete_device() and usb_put_dev() are called both if at76_init_new_device() fails in at76_probe(). But at76_delete_device() does usb_put_dev(priv->dev) itself that means double usb_put_dev().
