commit 7342adaa

vulkan/swapper: check queue present return later

During resizes, the VkQueuePresent can return OUT_OF_DATE and if a buffer
is displayed returning OUT_OF_DATE it would error out and stop the pipeline.

We already have a explicit check for OUT_OF_DATE and the same general
error check in the statements following so just use that code.
