[PATCH v2 15/15] KVM: VMX: Rename vmx_uret_msr's "index" to "slot"

[Sean Christopherson <sean.j.christopherson@xxxxxxxxx>]

Rename "index" to "slot" in struct vmx_uret_msr to align with the
terminology used by common x86's kvm_user_return_msrs, and to avoid
conflating "MSR's ECX index" with "MSR's index into an array".

No functional change intended.
