btrfs-progs: tests: Add test case to ensure btrfs check returns error for corrupted qgroups

Since the test case uses run_mustfail(), which is pretty easy pass due to
other unexpected problems, so here an extra run_check() is added to
ensure we don't only report qgroup error, but also fix it without
problem.
