xen: Don't peek behind the BlockDriverState abstraction
First offender is xen_config_dev_blk()'s use of disk->bdrv->filename.
Get the filename from disk->opts instead. Same result, except for
snapshots: there, we now get the filename specified by the user
instead of the name of the temporary image created by bdrv_open().
Should be an improvement.
Second offender is blk_init()'s use of blkdev->bs->drv->format_name.
Simply use the appropriate interface to get the format name.
