The problem occurs when RAID10 array under rebuild
(after one disk fails) is assembled incrementally.
Mdadm tries to start array just after adding the third disk
and the volume is assembled incorrectly (in degraded state).

The cause is that container_enough depends on
newly missing disks which are checked incorrectly now.
They should be checked using always the first map.
