vulkan/wsi: check if image info was already freed

We set the different data being freed to NULL after freeing it, and
checks for NULL before freeing it.

This fixes several double free crash with v3dv, when running OOM wsi
tests, like for example:
dEQP-VK.wsi.xlib.swapchain.simulate_oom.composite_alpha

Although note that only one person got those on a new fresh install of
the Raspbian OS, so this problem was rare.

Fixes: 5b13d74583 ("vulkan/wsi/drm: Break create_native_image in pieces")
