[RFC PATCH 44/67] KVM: VMX: Modify NMI and INTR handlers to take intr_info as param

[isaku . yamahata]

From: Sean Christopherson <sean.j.christopher...@intel.com>

Pass intr_info to the NMI and INTR handlers instead of pulling it from
vcpu_vmx in preparation for sharing the bulk of the handlers with TDX.
