ia64: Fix xc_save error reporting

This is the patch for error reporting on ia64 that has a special
handling in comparison with i386/x86_64 platforms. This is pretty
straight-forward just to fail on "cannot map mfn page" message instead
of continue since the memory is not being correctly mapped using the
xc_map_foreign_range() function.
