Grow: increase raid_disks before adding specific spares.
When we add spared that have been targeted at a specific slot,
we need raid_disks to be bigger than the slot number.
But currently we don't increase raid_disks until after we add
these spares.
So introduce an early increase of raid_disks to allow the spares
to be added.
