net: renesas: rswitch: avoid use-after-put for a device tree node

[ Upstream commit 66b7e9f85b8459c823b11e9af69dbf4be5eb6be8 ]

The device tree node saved in the rswitch_device structure is used at
several driver locations. So passing this node to of_node_put() after
the first use is wrong.

Move of_node_put() for this node to exit paths.
