* normal/misc.c (grub_normal_print_device_info): Do not probe for
	filesystem when dev->disk is unset.
	Do probe for filesystem even when dev->disk->has_partitions is set.
	In case a filesystem is found, always report it.
	In case it isn't, if dev->disk->has_partitions is set, report that
	a partition table was found instead of reporting that no filesystem
	could be identified.
