Invalid handle in create_display_plane_surface

Invalid handle in create_display_plane_surface

This test attempts to create a display plane surface but incorrectly
fills in the VkDisplaySurfaceCreateInfo with an index into dEQP's array
of display modes instead of the VkDisplayModeKHR handle itself.

The app is required to specify a valid handle.

An invalid handle results in undefined behaviour.

Affects:

dEQP-VK.wsi.display.create_display_plane_surface

Components: Vulkan
VK-GL-CTS issue: 906
