KVM: nVMX: initialize PML fields in vmcs02

commit 1fb883bb827ee8efc1cc9ea0154f953f8a219d38 upstream.

L2 was running with uninitialized PML fields which led to incomplete
dirty bitmap logging. This manifested as all kinds of subtle erratic
behavior of the nested guest.

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