Issue found on Bionic s390x s2lp3 / kernel02 with 4.15.0-145.149-generic

This is not a regression since the test was run with the latest hirsute-WIP branch, with upstream tip c986dbe867053 ("x86/vmx: skip error-code delivery tests for #CP").

Test aborted with Unexpected external call interrupt (code 0x1201), log:
