KVM: x86: Always set kvm_run->if_flag
commit c5063551 upstream. The kvm_run struct's if_flag is a part of the userspace/kernel API. The SEV-ES patches failed to set this flag because it's no longer needed by QEMU (according to the comment in the source code). However, other hypervisors may make use of this flag. Therefore, set the flag for guests with encrypted registers (i.e., with guest_state_protected set).
