If parsing a child fails, the failed child is\nnot counted in nr_children and the parent may be left with a children array\nthat bl_free_device() will not release when nr_children is zero.\n\nRelease the failed child and the already parsed children before returning the\nerror.  Also make bl_free_device() release the child array whenever the\nchildren pointer is set, so that partially initialised concat or stripe\ndevices are cleaned up correctly.\n\nbl_parse_scsi() can also fail after assigning d->bdev_file and dropping the\nfile reference.
