[IA64] vti domain save/restore: fix stack unwinder

fix stack unwinder.
- fix find_save_locs() and unw_unwind().
  instruction pointer check should be suite for xen.
- fix unw_unwind_to_user()
  VTi domain fault handler doesn't always updatevcpu->on_stack so that
  the pUStk check fails. Add more checking to stop winding.
