[Qemu-block] [PATCH v2] iotests: Make 200 run on tmpfs

[Max Reitz]

200 currently fails on tmpfs because it sets cache=none.  However,
without that (and aio=native), the test still works now and it fails
before Jeff's series (on fc7dbc119e0852a70dc9fa68bb41a318e49e4cd6).  So
we can probably remove the aio=native safely, and replace cache=none by
cache=$CACHEMODE.
