Suggestion, please use "FIXME-64" instead of fixme so it's easier to
clean this up later.

Might as well fix this in the initial patch series, earlier --- and
let's *not* make it be an inline function.  Yeah, we call
ext2fs_group_of_blk and ext2fs_group_of_ino a fair amount, but #1, on
32-bit machines, the 64 bit arithmemtic makes the function bigger, and
#2, modern CPU's have greatly reduced the cost of procedure
activations.
