vulkan: filter duplicate pNext struct at device creation

Recently, Indiana Jones and The Great Circle messed up this by adding
duplicates and this was causing the game to crash at launch.

Of course, this was an application bug that VVL was also able to catch
but I think maybe Mesa should ignore those instead of failing to create
the logical device.
