btrfs: tests/qgroup: Fix wrong tree backref level
The extent tree of the test fs is like the following: BTRFS info (device (null)): leaf 16327509003777336587 total ptrs 1 free space 3919 item 0 key (4096 168 4096) itemoff 3944 itemsize 51 extent refs 1 gen 1 flags 2 tree block key (68719476736 0 0) level 1 ^^^^^^^ ref#0: tree block backref root 5 And it's using an empty tree for fs tree, so there is no way that its level can be 1. For REAL (created by mkfs) fs tree backref with no skinny metadata, the result should look like: item 3 key (30408704 EXTENT_ITEM 4096) itemoff 3845 itemsize 51 refs 1 gen 4 flags TREE_BLOCK tree block key (256 INODE_ITEM 0) level 0 ^^^^^^^ tree block backref root 5 Fix the level to 0, so it won't break later tree level checker.
