[PATCH] powerpc-km82xx.c: replace of_node_put with __free improves cleanup

[David Hunter]

The use of the __free function allows the cleanup to be based on scope
instead of on another function called later. This makes the cleanup
automatic and less susceptible to errors later.

This code was compiled without errors or warnings.
