nvmem: meson-efuse: Replacing the use of of_node_put to __free
Use __free for device_node values, and thus drop calls to
of_node_put.
The goal is to reduce memory management issues by using this
scope-based of_node_put() cleanup to simplify function exit
handling. When using __free a resource is allocated within a
block, it is automatically freed at the end of the block.
