nouveau: Fix build, invalid extern "C" around header inclusion.

A previous patch to fix header inclusion within extern "C" neglected
to fix the occurences of this pattern in nouveau files.

When the helper to detect this issue was pushed to master, it broke
the build for the nouveau driver.  This patch fixes the nouveau build.
