Subject: [PATCH 4.16 003/279] KVM: X86: fix incorrect reference of trace_kvm_pi_irte_update

4.16-stable review patch.  If anyone has any objections, please let me know.

From: hu huajun <huhuajun@...ux.alibaba.com>

[ Upstream commit 2698d82e519413c6ad287e6f14b29e0373ed37f8 ]

In arch/x86/kvm/trace.h, this function is declared as host_irq the
first input, and vcpu_id the second, instead of otherwise.
