Pavel Skripkin 5f7c1c46f5 drivers: net: fix memory leak in atusb_probe 
commit 6b9fbe16955152626557ec6f439f3407b7769941 upstream.

syzbot reported memory leak in atusb_probe()[1].
The problem was in atusb_alloc_urbs().
Since urb is anchored, we need to release the reference
to correctly free the urb

backtrace:
