    PowerMax Driver - Fix non-temporary snapshot delete

    Fix bug where non-temporary snapshots were being
    deleted from volume when do_sync_check is called
    for that volume, caused by missing check for
    temporary snapshot naming convention. Fixed by
    adding this check back into the conditional
    that determined if a snapshot should be deleted.
