[PATCH] phy: tegra: xusb: Call of_node_put(np) only once in tegra_xusb_padctl_get()

An of_node_put(np) call was immediately used after a pointer check
for a of_find_device_by_node() call in this function implementation.
Thus call such a function only once instead directly before the check.

This issue was transformed by using the Coccinelle software.
