[XFS] Put the correct offset in dirent d_off
The recent filldir regression fix was not putting the correct d_off in
each dirent. This was resulting in incorrect cookies being passed to dmapi
ioctls and the wrong offset appearing in the dirents. readdir was
unaffected as the filp->f_pos was being updated with the correct offset
and this was being written into the last dirent in each buffer. Fix the
XFS code to do the right thing.
