Fix some serious brain damage in the default block/frag/cpg parameters

Browse Source 
that are used if none at all are specified for a partition. Don't
keep replaying the last field if we run out of fields when processing

More work here is required. I think disklabel should not attempt
to choose default filesystem parameters, and instead let newfs pick
any defaults if required.
