[PULL 69/69] qemu-iotests: restrict 264 to qcow2 only

[Max Reitz]

From: Vladimir Sementsov-Ogievskiy <address@hidden>

264 is unprepared to run with different formats, for example luks needs
handling keys, cloop doesn't support image creation, vpc creates image
larger than requested (which breaks "Backup completed: 5242880" in test
output).

The test is here to check nbd-reconnect feature and we actually don't
need it for all formats. Let's restrict it to qcow2 only.
