[DLM] fix size of STATUS_REPLY message
When the not_ready routine sends a "fake" status reply with blank status flags, it needs to use the correct size for a normal STATUS_REPLY by including the size of the would-be config parameters. We also fill in the non-existant config parameters with an invalid lvblen value so it's easier to notice if these invalid paratmers are ever being used.
