[PATCH v2 15/17] locking/lockdep: Adjust selftest case for recursive read lock

Now that we support recursive read locks, a previously failed case:

----------------------------------------------------------------------------
| spin |wlock |rlock |mutex | wsem | rsem |
--------------------------------------------------------------------------
mixed read-lock/lock-write ABBA: |FAILED| | ok |

can be added back. Now we have:

Good, all 262 testcases passed!

See the case in: e91498589746065e3a ("Add mixed read-write ABBA tests")
