Problem: We keep pinning pages in dict_stats_analyze_index_below_cur(), but doesn't release these pages. When we have a relative small buffer pool size, and big innodb_stats_persistent_sample_pages, there will be no free pages for use. Solution: Use a separate mtr in dict_stats_analyze_index_below_cur(), and commit mtr before return. Reviewed-by: Jimmy Yang <jimmy.yang@oracle.com> RB: 11362
