KVM: nVMX: do not leak PML full vmexit to L1

The PML feature is not exposed to guests so we should not be forwarding
the vmexit either.

This commit fixes BSOD 0x20001 (HYPERVISOR_ERROR) when running Hyper-V
enabled Windows Server 2016 in L1 on hardware that supports PML.

Fixes: 843e4330573c ("KVM: VMX: Add PML support in VMX")
