Vulkan: Fix HDR pipeline init indentation and use sdr_render_pass

Fix indentation of the HDR pipeline initialization block inside
vulkan_init_pipelines to use consistent 3-space indentation matching
the surrounding code style.

Use vk->sdr_render_pass instead of vk->render_pass when restoring
pipeline state after the HDR tonemapping readback pipeline setup,
to correctly reference the SDR render pass.
