[PATCH 06/22] KVM: VMX: Call vmx_get_cpl() directly in handle_dr()

[Sean Christopherson]

Use vmx_get_cpl() instead of bouncing through kvm_x86_ops.get_cpl() when
performing a CPL check on MOV DR accesses.  This avoids a RETPOLINE (when
enabled), and more importantly removes a vendor reference to kvm_x86_ops
and helps pave the way for unexporting kvm_x86_ops.
