KVM: VMX: Get rid of eVMCS specific VMX controls sanitization
With the updated eVMCSv1 definition, there's no known 'problematic'
controls which are exposed in VMX control MSRs but are not present in
eVMCSv1: all known Hyper-V versions either don't expose the new fields
by not setting bits in the VMX feature controls or support the new
eVMCS revision.
Get rid of VMX control MSRs filtering for KVM on Hyper-V.
Note: VMX control MSRs filtering for Hyper-V on KVM
(nested_evmcs_filter_control_msr()) stays as even the updated eVMCSv1
definition doesn't have all the features implemented by KVM and some
fields are still missing. Moreover, nested_evmcs_filter_control_msr()
has to support the original eVMCSv1 version when VMM wishes so.
