[IA64] Kill PM timer

The release proceeding of domain resources forgot to stop (or kill)
PM timer, and freed the domain structure.
VMX flag of VCPU#0 was not set when VHPT allocation for VCPU#0
failed.  For this reason, domain_relinquish_resources() did not
call vmx_relinqush_guest_resources().  But the domain structure
was freed.  As a result, timer_softirq_action() lose sight of
the callback function for PM timer.
