[Mesa-dev] [PATCH] vulkan/wsi: use the drmGetDevice2() API

From: Emil Velikov <emil.velikov at collabora.com>

On older kernels, the drmGetDevice() call will wake up all the GPUs
on the system, while fetching the PCI revision.

Use the 2 version of the API and pass flags == 0, so we don't fetch the
device PCI revision, since we don't need that information.
