d3d11: Add a missing "extern" for a variable declaration

If the "extern" is skipped, the declaration turns into a definition
of uninitialized data, which can be silently overridden by an
initialized definition. But here a plain declaration is what is
intended.

(cherry picked from commit c455866ff0c0113de4ee02bacece73b2f9938143)
