Boqun Feng 8ef7ca7512 lockdep/selftest: Add more recursive read related test cases
Add those four test cases:

1.	X --(ER)--> Y --(ER)--> Z --(ER)--> X is deadlock.

2.	X --(EN)--> Y --(SR)--> Z --(ER)--> X is deadlock.

3.	X --(EN)--> Y --(SR)--> Z --(SN)--> X is not deadlock.

4.	X --(ER)--> Y --(SR)--> Z --(EN)--> X is not deadlock.

Those self testcases are valuable for the development of supporting
recursive read related deadlock detection.
