usb: dwc3: st: Add of_dev_put() in probe function
In function st_dwc3_probe, variable child_pdev takes the value returned
by of_find_device_by_node, which gets a device pointer but does not put
it. If child_pdev is not put before the probe function returns, it may
cause a reference leak. Hence put child_pdev after its last usage.
Issue found with Coccinelle.
