Subject: [patch V3 53/64] lib/test_lockup: Adapt to changed variables.

From: Sebastian Andrzej Siewior <bigeasy@...utronix.de>

The inner parts of certain locks (mutex, rwlocks) changed due to a rework for
RT and non RT code. Most users remain unaffected, but those who fiddle around
in the inner parts need to be updated.

Match the struct names to the new layout.
