* partmap/gpt.c (grub_gpt_magic): Add `0x' qualifier to each member,
        since they were intended to be in hex.  This didn't break previously
        because of a bug in gpt_partition_map_iterate() (see below).

        (gpt_partition_map_iterate): Replace `grub_memcmp' with `! grub_memcmp'
        when checking the validity of GPT header.
        Remove `partno', since it always provides the same information as `i'.
