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.
