Detail: don't assume a particular 'disk' number of missing devices. 

When a particular raid-disk is missing, we don't know which disk number
it should have, and reporting a number could result in duplicate
numbers (with v1.x metadata - never with the old 0.90).

So set the default to -1 and recoginise that when printing.
