12d7b3bbd3333cededd3b695501d8d247239d769 iotests: add test for stream job with an unaligned prefetch read
Previously, bdrv_pad_request() could not deal with a NULL qiov when
a read needed to be aligned. During prefetch, a stream job will pass a
NULL qiov. Add a test case to cover this scenario.
By accident, also covers a previous race during shutdown, where block
graph changes during iteration in bdrv_flush_all() could lead to
unreferencing the wrong block driver state and an assertion failure
later.
