KVM: x86: Remove VT-d mention in posted interrupt tracepoint 



The kvm_pi_irte_update tracepoint is called from both SVM and VMX vendor
code, and while the "posted interrupt" naming is also adopted by SVM in
several places, VT-d specifically refers to Intel's "Virtualization
Technology for Directed I/O".
