In [cublas_lt_matmul.cc](https://github.com/tensorflow/tensorflow/blob/305c2c09dd998397f52da79650b36c35ff211225/tensorflow/compiler/xla/service/gpu/runtime/cublas_lt_matmul.cc#L140)，we will get all valid algorithms from cublasLtMatmulAlgoGetHeuristic()，and then select the i-th from  parameter "algorithm". However, it seems this "algorithm" parameter is not correctly set in gemm_algorithm_picker. 

This pr fix the bug, and I run several tests on A800, it can help to improve the gemm performance.
