In lowmem mode with '--repair', check_chunks_and_extents_v2()
will fix accounting in block groups and clear the error
bit BG_ACCOUNTING_ERROR.
However, return value of check_btrfs_root() is 0 either 1 instead of
error bits.
If extent tree is on error, lowmem repair always prints error and
returns nonzero value even the filesystem is fine after repair.
So let @err contains bits after walk_down_tree_v2().
