ia64: Fix xc_save error reporting

Hi,
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.

This patch has been originally done for RHEL-5 version of Xen, tested and working fine on RHEL-5 but when I had a look at Xen-unstable I saw that is *may* be the issue there as well. Unfortunately I'm not having any ia64 machine where I can install Xen-unstable so could somebody please test this patch on Xen-unstable ? Nevertheless, since the code is pretty similar for both RHEL-5 Xen and Xen-unstable it should work the same, i.e. it should be working but unfortunately I can't test it :(

Thanks a lot,
Michal
