[PATCH 2/4] FIX: Fiddle raid_disks number for external metadta

[Adam Kwolek <adam.kwolek@intel.com>]

For external metadata migration is started already.
For native metadata migration starts when md is pushed to reshape state.
Change raid disks to currently present in md to calculate required
configuration change in analyse_change() and add required disks to md.
