Fix VkPipelineLayout use after free

The test destroys pipeline layout, used to create the graphics pipeline,
before the command buffer using this pipeline is recorded.

This is invalid according to spec:
	"A VkPipelineLayout object must not be destroyed while any
	command buffer that uses it is in the recording state."

Components: Vulkan

VK-GL-CTS Issue: 1134

	dEQP-VK.draw.differing_interpolation.*
