soc: qcom: mem-offline: Ignore hotplug notification for other blocks 



Other blocks that don't belong to mem-offline can still be offlined and
onlined if their 'removable' is set. This will call our notifier registered
to this driver. We don't want to do any AOP notification or record stats
for blocks that don't belong to mem-offline. Hence, just log the action on
those blocks and avoid performing any further actions.
