Input: sparcspkr - fix refcount leak in bbc_beep_probe
of_find_node_by_path() calls of_find_node_opts_by_path(), which returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak. Fixes: 9c1a5077fdca ("input: Rewrite sparcspkr device probing.")
