libext2fs: Fix counting routines in blknum.c to take/return __u32 counts

Several routines in lib/ext2fs/blknum.c:

        ext2fs_bg_free_blocks_count()
        ext2fs_bg_free_inodes_count()
        ext2fs_bg_used_dirs_count()
        ext2fs_bg_itable_unused()

and their _set() counterparts, operate as if they are dealing with
blk64_t quantities, but they should be dealing with __u32 counts
instead.
