ZFS send streams include a feature flag DMU_BACKUP_FEATURE_LARGE_BLOCKS to indicate the presence of large blocks in the dataset. On the sending side, this flag is included if the `-L` flag is passed to `zfs send` and the feature is active in the dataset. On the receive side, the stream is refused if the feature is active in the destination dataset but the stream does not include the feature flag. The problem is the feature is only activated when a large block is born. If a large block has been born in the destination, but never the source, the send can't work. This can arise when sending streams back and forth between two datasets. This commit fixes the problem by always activating the large blocks feature when receiving a stream with the large block feature flag.
