Use __free cleanup handler which ensures that the resource is freed when
it goes out of scope, thus removing the need to manually clean it up
using of_node_put.

Rob Herring <robh@kernel.org> sent a patch fixing similar cases in
property.c but seems to have missed this one. Please let me know if this
is mistake, or if it was left unchanged for a reason.
