  To: Jens Axboe, Pavel Begunkov; +Cc: io-uring, Dylan Yudaken

This test was skipping in IORING_SETUP_DEFER_TASKRUN as it was not
flushing the work queue before checking for completions.

Additionally fix the test to only skip if it is the first loop.

Fixes: f91105d54955 ("update existing tests for defer taskrun")
