FIX: restart reshape when reshape process is stopped just between 2 reshapes
When reshape is restarted from '0', very begin of array it is possible that for external metadata reshape and array configuration doesn't happen. Check if md has the same opinion, and reshape is restarted from 0. If so, this is regular reshape start after reshape switch in metadata to next array only.
