In gfs2_put_super(), ensure quota is cleaned up by calling gfs2_quota_cleanup() regardless of whether the filesystem is withdrawn. Also, after calling gfs2_make_fs_ro(), do not call gfs2_destroy_threads() and gfs2_quota_cleanup() again since gfs2_make_fs_ro() already calls them.
Linux kernel (gfs2) gfs2_put_super() cleanup flow = Call gfs2_quota_cleanup() in gfs2_put_super() whether the filesystem is withdrawn or not; do not rely on gfs2_destroy_threads() / gfs2_quota_cleanup() being handled solely by gfs2_make_fs_ro()
