i915: Silence warning: unused parameter warning in intel_bufferobj_buffer

intel_buffer_objects.c: In function 'old_intel_bufferobj_buffer':
intel_buffer_objects.c:471:17: warning: unused parameter 'flag' [-Wunused-parameter]

The parameter hasn't been used since the i915 and i965 drivers had their
breakup.  i965 got the flags, and i915 got to cry itself to sleep.
