…r 0.6.15 flashinfer 0.6.15 includes the fix for the missing multi-CTAs counter buffer initialization (flashinfer-ai/flashinfer#3433). Remove the _clear_multi_ctas_kv_counter_workspace workaround calls from run_generation() and run_mla_generation(), and drop the now-unused helper functions _clear_multi_ctas_kv_counter_workspace and _get_multi_ctas_kv_counter_size.
