* util/i386/pc/grub-mkimage.c (generate_image): If we included a drive
        in our prefix, set install_{dos,bsd}_part = -2 to indicate this can be
        skipped later.
        (main): If a memdisk was requested, add "(memdisk)" drive explicitly to
        the beginning of the prefix.

        * kern/i386/pc/init.c (make_install_device): Remove memdisk check.
        It is assumed that if we have a memdisk, grub-mkimage has set
        grub_prefix to include the "(memdisk)" drive in it.
