xfs: actually rebuild the parent pointer xattrs

Once we've assembled all the parent pointers for a file, we need to
commit the new dataset atomically to that file.  Parent pointer records
are embedded in the xattr structure, which means that we must write a
new extended attribute structure, again, atomically.  Therefore, we must
copy the non-parent-pointer attributes from the file being repaired into
the temporary file's extended attributes and then call the atomic extent
swap mechanism to exchange the blocks.
