[Mesa-dev] [PATCH shader-db 3/3] intel_stub: Return a non-zero context ID.

[Kenneth Graunke]

Recent Mesa has started detecting a hardware context ID of zero (which
is bogus - it's the default context ID) and failing GL context creation.
Previously it saw that the ioctl returned success and happily proceeded.

Don't bother assigning a real ID, but do assign a non-zero value.
