Introduce a new mode for the rqspinlock stress test that exercises a
deadlock that won't be detected by the AA and ABBA checks, such that we
always reliably trigger the timeout fallback. We need 4 CPUs for this
particular case, as CPU 0 is untouched, and three participant CPUs for
triggering the ABBCCA case.

Refactor the lock acquisition paths in the module to better reflect the
three modes and choose the right lock depending on the context.
