net: hns3: code optimization for hclge_rx_buffer_calc
There are four steps to calcuate the rx private buffer, each step can be done in a function to avoid code duplication and aid code readability. This patch adds three separate functions do the job. Also, the function name more or less make the comment redundant, so remove some obvious comment.
