As FADump does not require an explicit elfcorehdr update whenever there is CPU hotplug event so let's stop kdump service reload for FADump when CPU hotplug event is triggered. A new label is added to handle CPU and memory hotplug events separately. The updated CPU hotplug event handler make sure that kdump service should not be reloaded when FADump is configured.
