    BZ#717658 - Simplify SDF.produce()
    
    produce() calls lookup(),
    lookup() calls (blockSD, localFsSD, nfsSD).findDomain(),
    findDomain() calls __init__(),
    __init__() calls findDomainPath(),
    findDomainPath() will return or raise StorageDomainDoesNotExist!
    
    Never None, never a false value, no need for this check.
