From: Dan Williams <dan.j.williams@xxxxxxxxx>
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.
