I want to use extent tree v2 in our self tests to make sure the extent
buffer related tests all do the correct thing, which requires setting
BTRFS_FEATURE_INCOMPAT_EXTENT_TREE_V2 on the fs_info.  However we won't
be having per-block group global roots for the dummy fs_info, so add
another check to btrfs_global_root_id to bail if we have DUMMY set.
