* fs/reiserfs.c (grub_reiserfs_get_key_v2_type): Handle endianness
    correctly.
    (grub_reiserfs_get_key_offset): Likewise.
    (grub_reiserfs_set_key_offset): Likewise.
    (grub_reiserfs_set_key_type): Likewise.
    (grub_reiserfs_iterate_dir): Return 1 if found, otheriwise 0.

    (GRUB_REISERFS_KEYV2_BITFIELD): Undefined. Probably it would be
    better to remove the bitfield version completely.
