* 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.
