i915: Correctly set the OQ counter bits.
While we may provide the extension, we need to tell applications that they
can't actually use it:
An implementation can either set QUERY_COUNTER_BITS_ARB to the
value 0, or to some number greater than or equal to n. If an
implementation returns 0 for QUERY_COUNTER_BITS_ARB, then the
occlusion queries will always return that zero samples passed the
occlusion test, and so an application should not use occlusion
queries on that implementation.
