Couple macro are duplicated defined and they are not used. So
to tame gcc, let's remove them.

fs/hfsplus/part_tbl.c:26:0: warning: macro "HFS_DRVR_DESC_MAGIC" is not
used [-Wunused-macros]
fs/hfsplus/part_tbl.c:30:0: warning: macro "HFS_MFS_SUPER_MAGIC" is not
used [-Wunused-macros]
fs/hfsplus/part_tbl.c:21:0: warning: macro "HFS_DD_BLK" is not used
[-Wunused-macros]
