HID: elo: fix memory leak in elo_probe
When hid_parse() in elo_probe() fails, it forgets to call usb_put_dev to
decrease the refcount.
Fix this by adding usb_put_dev() in the error handling code of elo_probe().
Fixes: fbf42729d0e9 ("HID: elo: update the reference count of the usb device structure")
