usb: dwc3-generic: Return early when there is no child node
The current error check for device_find_first_child is not working as
expected, the documentation for device_find_first_child mention:
@devp: Returns first child device, or NULL if none
Return: 0
Change to return early when there is no child node to avoid any possible
null pointer dereference.
