Both DDT log and BRT counters we read on pool import and then only append or overwrite in full blocks. We don't need them in DMU or ARC caches. Fortunately we have DMU_UNCACHEDIO for this now. Even more we don't need BRT in non-evictable metadata DMU caches, since it will likely never fit there, while block the cache from its original users. Since DMU_OT_IS_METADATA_CACHED() has no way to differentiate the new metadata types, mark BRT with storage type of DMU_OT_DDT_ZAP. As side effect it will also put it on dedup device, but that should actually be right.
