KVM: SEV: initialize regions_list of a mirror VM
This was broken before the introduction of KVM_CAP_VM_MOVE_ENC_CONTEXT_FROM, but technically harmless because the region list was unused for a mirror VM. However, it is untidy and it now causes a NULL pointer access when attempting to move the encryption context of a mirror VM. Fixes: 54526d1fd593 ("KVM: x86: Support KVM VMs sharing SEV context") Message-Id: <20211123005036.2954379-7-pbonzini@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
