Initialize resourceImgLayout before use for all code paths

Without this fix when updateDescriptorSet() is called in
BarrierTestInstance::iterate() debug builds for Vulkan CTS will
complain that resourceImgLayout is used without being initialized.

Affects:

dEQP-VK.ray_tracing_pipeline.barrier.*

Components: Vulkan

VK-GL-CTS issue: 2669

Change-Id: If320ac561cf278a9697ca33d302a1130db29fdb7
