[PATCH v2 06/11] KVM: x86: Plumb the src/dst operand types through to .check_intercept()

[Sean Christopherson]

When checking for intercept when emulating an instruction on behalf of L2,
forward the source and destination operand types to vendor code so that
VMX can synthesize the correct EXIT_QUALIFICATION for port I/O VM-Exits.
