memory: mtk-smi: fix device leak on larb probe
[ Upstream commit 9dae65913b32d05dbc8ff4b8a6bf04a0e49a8eb6 ]
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")
