[PATCH] regulator: Call of_node_put() only once in rzg2l_usb_vbus_regulator_probe()

[Markus Elfring <Markus.Elfring@web.de>]

From: Markus Elfring <elfring@users.sourceforge.net>

An of_node_put(config.of_node) call was immediately used after a pointer
check for a devm_regulator_register() 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.
