systemd-modules-load.service automatically tries to load the pkey module on systems that have MSA. Pkey also requires the MSA3 facility and a bunch of subfunctions. Failing with -EOPNOTSUPP makes "systemd-modules-load.service" fail on any system that does not have all needed subfunctions. For example, when running under QEMU TCG (but also on systems where protected keys are disabled via the HMC). Let's use -ENODEV, so systemd-modules-load.service properly ignores failing to load the pkey module because of missing HW functionality.
