When multipath was selecting an alias for a device on reload, if it
didn't have an explicit alias, and user_friendly_names wasn't set,
multipath would use the existing alias, if one existed. This made it
impossible to turn off user_friendly_names, and then reconfigure to
change the device names back to wwids.
Instead, multipath should just use the wwid as an alias, if that's
what it's configured to do, regardless of the existing name.
