pinctrl: pinconf-generic: add missing of_node_put()

Browse source 
[ Upstream commit 5ead932898 ]

of_node_put() needs to be called when jumping out of the loop, since
for_each_available_child_of_node() will increase the refcount of node.

Fixes: c7289500e2 ("pinctrl: pinconf-generic: scan also referenced phandle node")
