[RFC tip/locking/lockdep v4 14/17] Revert "locking/lockdep/selftests: Fix mixed read-write ABBA tests"

[Boqun Feng]

This reverts commit d82fed75294229abc9d757f08a4817febae6c4f4.

Since we now could handle mixed read-write deadlock detection well, the
self tests could be detected as expected, no need to use this
work-around.
