usb: core: add missing of_node_put() in usb_of_has_devices_or_graph

The for_each_child_of_node() macro requires an explicit call to
of_node_put() on early exits to decrement the child refcount and avoid a
memory leak.
The child node is not required outsie the loop, and the resource must be
released before the function returns.

Add the missing of_node_put().
