[IA64] VTI: Fix two bugs

1. Vmx_check_pending_irq should not be called in vmx_vcpu_set_eoi,
because vmx_vcpu_increment_iip is called after vmx_vcpu_set_eoi. That
is, the first instruction of guest interrupt handler will be skipped.
2. Remove code segment which was used to send events to VTIdomain, when
dom0 was VTIdomain. This is not needed any more, and will cause
VTIdomain on SMP-HOST complain "Unexpected interrupt ..." .
