[I] [Improve][SDK] Add out-of-bounds check when in getClientByRoundRobin() [inlong]

[via GitHub]

gosonzhang opened a new issue, #11717:
URL: https://github.com/apache/inlong/issues/11717

   ### Description
   
   When the getClientByRoundRobin() function gets the DataProxy node, it uses 
[1]:
    curNode = curNodes.get(Math.abs(startPos++) % curNodeSize);
   
   Some users reported that the array is out of bounds. Although the code 
review shows that it does not appear here, in order to avoid this situation, 
rewrite it here to eliminate this type of problem
