Fix large dnode send stream flag conflict
Bit 21 of the send stream flags was inadvertently used for two different features under concurrent development. To avoid any future compatibility problems the large dnode flag is being switched to bit 23 which is unused. The large dnode feature has only been present in pre-releases of ZoL and dnodesize defaults to legacy which is compatible with existing OpenZFS implementations. Users with dnodesize=auto needing to use zfs send/recv must update ZoL on both the source and destination systems.
