We do not keep redundant copies of the metadata - the data is kept only on the 
first pv when you create a vg (--metadataignore y).

The metadata area on the next pvs is unused, but having it allows using this 
area on these pvs later.

Since we use 128 megabytes for each metadata area, this change save 256 
megabytes per pv, which is not very interesting. Users are heaving terabytes 
and they do not care about those 256 megabytes.
