Re: [libvirt] [PATCH] qemu: Check for iotune_max support properly

Commit d506a51aeb2a7a7b0c963f760e32b94376ea7173 meant to check for QEMU_CAPS_DRIVE_IOTUNE_MAX, but checked for QEMU_CAPS_DRIVE_IOTUNE instead. That's clearly visible from the diff, but it got in. Because of that, we were supplying information unknown for QEMU if it wasn't new enough and we couldn't even properly handle the error, leading to "Unexpected error". Also iops_size came at the same time with all the other "_max" options, so check whether we're not setting that either if QEMU_CAPS_DRIVE_IOTUNE_MAX is not supported.
