selftests: ublk: add stress test for per io daemons
Add a new test_stress_06 for the per io daemons feature. This is just a
copy of test_stress_01 with the per_io_tasks flag added, with varying
amounts of nthreads. This test is able to reproduce a panic which was
caught manually during development [1]; in the current version of this
patch set, it passes.
Note that this commit also makes all stress tests using the
run_io_and_remove helper more stressful by additionally exercising the
batch submit (queue_rqs) path.
