Before the fix, teardown of a ublk server that was attempting to recover a device, but died when it had submitted a nonempty proper subset of the fetch commands to any queue would loop forever. Add a test to verify that, after the fix, teardown completes. This is done by: - Adding a new argument to the fault_inject target that causes it die after fetching a nonempty proper subset of the IOs to a queue - Using that argument in a new test while trying to recover an already-created device - Attempting to delete the ublk device at the end of the test; this hangs forever if teardown from the fault-injected ublk server never completed. It was manually verified that the test passes with the fix and hangs without it.
