mesa: Allow query of MAX_SAMPLES with EXT_framebuffer_multisample
Previously queries of MAX_SAMPLES were only allowed with
ARB_framebuffer_object, but EXT_framebuffer_multisample also enables
this query. This seems to only effect the i915. All other drivers
support both extensions or neither extension.
This patch is based on a patch that Kenneth sent along with the report.
