Change initializer for array of structures to avoid GCC bug

Works around the following gcc 4.8.4 internal compiler error:

    vktReconvergenceTests.cpp:1169:35: internal compiler error: in gimplify_init_constructor, at gimplify.c:4271
       SubgroupState stateStack[10] = {};

Components: Vulkan
Affected tests: dEQP-VK.reconvergence.*
VK-GL-CTS issue: 3001
