Subject: [PATCH] pstore/ram: Avoid possible failure of dummy device unregister

If create dummy platform device failed, dummy variable should not
been set as NULL. Because the following platform_device_unregister()
will judge if the dummy is NULL or not, if dummy is NULL nothing
happen for unregister flow.
