Here's a small followup fix for this one that hopefully addresses the
issue discovered by Linaro's automated pre-commit tester (reported to
me via Maxim, thanks!).

This is probably obvious if the parent patch is OK.

    OpenMP: Fix map-arrayofstruct-{2,3}.c tests for shared-memory systems
    
    This is a small fix for two testcases when offload_device_nonshared_as
    returns false, e.g. for systems not using GPU offloading.
