[Qemu-devel] [PATCH v4 13/14] iotests: qcow2's encrypt.format is now optional

[Max Reitz <mreitz@redhat.com>]

Remove the encrypt.format option from the two blockdev-add test cases
for encrypted qcow2 images in 087 to explicitly test that this parameter
is now optional.

Additionally, show that explicitly specifying encrypt.format=auto works
just as well, the same for specifying the correct format
(encrypt.format=luks here), and that specifying the wrong format
(encrypt.format=aes) results in an error.

While touching this test case, reduce the LUKS iteration time to 10 so
the test stays reasonably fast.
