[PATCH 5.1 053/138] KVM: nVMX: use correct clean fields when copying from eVMCS

[Greg Kroah-Hartman]

[ Upstream commit f9bc5227652df4900eff12a9b8b38e9a8c7c78ea ]

Unfortunately, a couple of mistakes were made while implementing
Enlightened VMCS support, in particular, wrong clean fields were
used in copy_enlightened_to_vmcs12():
- exception_bitmap is covered by CONTROL_EXCPN;
- vm_exit_controls/pin_based_vm_exec_control/secondary_vm_exec_control
  are covered by CONTROL_GRP1.

Fixes: 945679e301ea0 ("KVM: nVMX: add enlightened VMCS state")
