xfs: remove the data_dotdot_offset field in struct xfs_dir_ops

Browse Source 
The data_dotdot_offset value is always equal to data_entry_offset plus
the fixed size of the "." entry.  Right now calculating that fixed size
requires an indirect call, but by the end of this series it will be
an inline function that can be constant folded.
