Unlike DDT, where ZAP values may have different lengths due to compression, all BRT entries are identical 8-byte counters. It does not make sense to first fetch the length only to assert it. zap_lookup_uint64() is specifically designed to work with counters of different size and should return error if something odd found. Calling it straight allows to save some measurable CPU time.
