block: Don't probe for unknown backing file format If a qcow2 image specifies a backing file format that doesn't correspond to any format driver that qemu knows, we shouldn't fall back to probing, but simply error out. Not looking up the backing file driver in bdrv_open_backing_file(), but just filling in the "driver" option if it isn't there moves us closer to the goal of having everything in QDict options and gets us the error handling of bdrv_open(), which correctly refuses unknown drivers.
