Following up on r1430302, fix several compile errors that I
didn't see locally and didn't produce test errors.

* subversion/libsvn_wc/externals.c
  (close_file): Update caller.

* subversion/libsvn_wc/tree_conflicts.c
  (svn_wc__add_tree_conflict): Update caller.

* subversion/libsvn_wc/workqueue.c
  (run_set_text_conflict_markers): Update caller.
