[PATCH v3 0/3] test-ww_mutex: Miscellaneous fixes

This series fixes:
     - module cleanup
     - error propagation from stress workers
     - transient -EDEADLK handling in test_cycle_work()

The series is re-based on v7.2-rc6 and has been tested on a 96-CPU
x86_64 bare-metal system and a 160-CPU arm64 bare-metal system. With
the test "stress_inorder_work" disabled, both systems completed 100
iterations of tools/testing/selftests/locking/ww_mutex.sh successfully
with the self-test as a module. With the self-test as a built-in, the
systems survived:

	for N in {1..100}; do
	    echo 1 > /sys/kernel/test_ww_mutex/run_tests
	done

The main differences between the v2 contribution and this v3, is that
the last patch is removed.

  test-ww_mutex: Fix module cleanup
  test-ww_mutex: Report errors from stress workers
  test-ww_mutex: Handle transient -EDEADLK in test_cycle_work
