The change fixes a bug introduced by 2be2a3ff42a5, memory allocated
by kstrdup_const() must be always deallocated with kfree_const(),
otherwise there is a risk of kfree'ing ro memory.
Also remove unneeded of_node_put(), if for_each_compatible_node() body
execution is not terminated, this prevents from double kfree() in
OF_DYNAMIC build.
