[Qemu-block] qemu-iotests RC0+ status

[John Snow]

Hi, on Fedora 28 x64 host, as of 68f1b569 I'm seeing:

`./check -v -qcow`
        - occasional stall on 052
        - stalls on 216

`./check -v -qed`
        - stalls on 200

`./check -v -luks`
        - failures on 226.


052 is something I can't reproduce. The test takes quite a while, so
maybe at some points I am simply not being patient enough.


216 appears to have never worked for qcow1.


226 is my fault: the test doesn't handle LUKS well, because it sets
TEST_IMG to something sneaky:
'driver=luks,key-secret=keysec0,file.filename=/path/to/src/qemu/bin/git/tests/qemu-iotests/scratch/t.luks'
... my test expected this to be a real file and doesn't suffer this
particularly well. I've sent a patch.


200 appears to regress on this commit:
f45280cbf66d8e58224f6a253d0ae2aa72cc6280 is the first bad commit
