of_find_device_by_node() takes reference, we should use put_device()
to release it. when devm_kzalloc() fails, it doesn't have a
put_device(), it will cause refcount leak.
Add missing put_device() to fix this.

slot_errbuf_lock has declared and initialized by DEFINE_SPINLOCK,
so we don't need to spin_lock_init again, drop it.
