vulkan/wsi/wayland: fix crash when force_bgra8_unorm_first is true

Browse source 
When force_bgra8_unorm_first is true, we access display->formats and
change the order of certain formats. The final result is BGRA8_UNORM
being the first in the format list, as some clients require this.

But we are trying to do this before before setting up display->formats,
so it should result in a crash. Fix this by changing the order of
things. Now we first set up display->formats before trying to access it.
