[ Upstream commit b5c5b13cb45e2c88181308186b0001992cb41954 ]
of_find_compatible_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
Fixes: 796bcae7361c ("USB: powerpc: Workaround for the PPC440EPX USBH_23 errata [take 3]")
