net/hns3: fix unintended sign extension in dump operation

Browse Source 
There are coverity defects related "Unintended sign extension" in the
internal static function named hns3_get_regs_length used for dumping reg
operation.

This patch fixes them by replacing the data type of cmdq_lines,
common_lines, ring_lines and tqp_intr_lines with uint32_t in the inner
static function named hns3_get_regs_length of hns3 PMD driver.

Coverity issue: 349917, 349914
Fixes: 936eda25e8da ("net/hns3: support dump register")
