usb: ehci/ohci-exynos: Fix of_node_put() for child when getting PHYs

On enabling CONFIG_OF_SELFTEST which enables CONFIG_OF_DYNAMIC,
we found out that while getting PHYs for the controller we were
doing an extra of_node_put on the child node in our routines -
exynos_e/ohci_get_phy().
This child is however already put by of_get_next_available_child()
which does a of_node_put() on the "prev" node. So there's no point
in putting the same node again in our routine.
