KVM: nVMX: Remove outdated comments in nested_vmx_setup_ctls_msrs() 

nested_vmx_setup_ctls_msrs() initializes the vmcs_conf.nested,
which stores the global VMX MSR configurations when nested is
supported, regardless of any particular CPUID settings for one
VM.

Commit 6defc59184 ("KVM: nVMX: include conditional controls
in /dev/kvm KVM_GET_MSRS") added the some feature flags for
secondary proc-based controls, so that those features can be
available in KVM_GET_MSRS. Yet this commit did not remove the
obsolete comments in nested_vmx_setup_ctls_msrs().

Just fix the comments, and no functional change intended.
