TAKE - More conservative max file size.

[Eric Sandeen <sandeen@xxxxxxx>]

As Andi says, "it's generally safe to not challenge the 
mighty sign extension."  :)

So it's down to 8TiB files now on 4k page machines.  (Again, this is a
_Linux_ limitation, not XFS per se.)

The following file(s) were checked into:

Modid:  2.4.x-xfs:slinx:110614a
linux/fs/xfs/xfs_inode.h - 1.153
        - More conservative value for XFS_MAX_FILE_OFFSET - beware the sign 
extension
