Assemble: fix assembly in the delta_disks > max_degraded case 

Incremental assembly works on such an array because the kernel sees the
disk as in-sync and that the array is reshaping.  Teach Assemble() the
same assumptions.

This is only needed on kernels that do not initialize ->recovery_offset
when activating spares for reshape.
