aiol from ubuntu_stress_smoke_test ADT test failure with linux-hwe 4.15.0-129.132~16.04.1

[Kleber Sacilotto de Souza]

Testing failed on:
    ppc64el: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-xenial/xenial/ppc64el/l/linux-hwe/20201217_204555_e0436@/log.gz

The testcase is failing only with ppc64el, and only on xenial/linux-hwe (not on bionic/linux).

This is likely a testcase issue, probably caused by https://github.com/ColinIanKing/stress-ng/commit/08d42b48c4cb8c116a7644bb3485d3ef3d77c701.

The aiol stress-ng testcase is now fixed.
