i965/blorp: Get rid of redundant num_samples blorp param.
Previously, brw_blorp_params contained two fields for determining sample count: num_samples (which determined the multisample configuration of the rendering pipeline) and dst.num_samples (which determined the multisample configuration of the render target surface). This was redundant, since both fields had to be set to the same value to avoid rendering errors. This patch eliminates num_samples to avoid future confusion.
