loader: Remove extension enable checks

Apparently, the intent of Vulkan is to have the loader do no
run-time checking in each of the functions as to whether or not
the extension is enabled.  This should only be done in the
validation layers.

This resolves the crash Jeff was seeing in the Nvidia driver when
using the new extension.
