KVM: nVMX: Don't set 'dirty_vmcs12' flag on enlightened VMPTRLD
'dirty_vmcs12' is only checked in prepare_vmcs02_early()/prepare_vmcs02()
and both checks look like:
'vmx->nested.dirty_vmcs12 || evmptr_is_valid(vmx->nested.hv_evmcs_vmptr)'
so for eVMCS case the flag changes nothing. Drop the assignment to avoid
the confusion.
No functional change intended.
