Input: sparcspkr - fix refcount leak in bbc_beep_probe

Browse Source 
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: 9c1a5077fd ("input: Rewrite sparcspkr device probing.")
