Fix illegal memory access for robustness test

Don't subtract 3 from buffer pointer for VK_FORMAT_A2B10G10R10_UNORM_PACK32
alpha channel because this format is a deUint32 instead of Vec4.

Affects: dEQP-VK.robustness.vertex_access.a2b10g10r10_unorm_pack32.*

Components: Vulkan

VK-GL-CTS issue: 946
