[IA64] Fix PAL_HALT of dom0 for panic_notifier_list

Currently dom0 cannot call panic_notifier_list in panic().
This is caused by PAL_HALT called from smp_send_stop().
When dom0 calls PAL_HALT, Hypervisor reset system.
So if dom0 panic, we cannot use panic_notifier_list.
Current PAL_HALT of xen is different from ia64 specification.
This patch fixes this issue.
