Return the directory offset information when adding an entry to the
directory.
This offset will be used as the parent pointer offset in xfs_create,
xfs_symlink, xfs_link and xfs_rename.
[dchinner: forward ported and cleaned up]
[dchinner: no s-o-b from Mark]
[bfoster: rebased, use args->geo in dir code]
[achender: rebased, chaged __uint32_t to xfs_dir2_dataptr_t]
