(1) Fix that tooltip shows multiple values around both sides of the pointer. Fix #9829.
(2) Fix a probably typo (diff < maxDistance) introduced by https://github.com/apache/incubator-echarts/commit/4ef66e1d892485ced1dbfcf915135e7740bb7cc3
(3) Remove the previous logic to resolve #2869. Because currently if there are multiple values on the same axis tick, both of them will be found and displayed in tooltip by default. The related historical commits:
https://github.com/apache/incubator-echarts/commit/60d341f4ed9e33381099624962a8388eef8a9547  (fix #2869)
https://github.com/apache/incubator-echarts/commit/3426bd0e544b16f90a476cd36a79119c3570a63b  (support find multiple values on the same axis tick).
