memory: mtk-smi: fix device leak on larb probe
Make sure to drop the reference taken when looking up the SMI device
during larb probe on late probe failure (e.g. probe deferral) and on
driver unbind.
Fixes: cc8bbe1a8312 ("memory: mediatek: Add SMI driver")
Fixes: 038ae37c510f ("memory: mtk-smi: add missing put_device() call in mtk_smi_device_link_common")
