Subject: [PATCH net-next 03/12] net: hns3: modify base parameter of kstrtouint in hclge_dbg_dump_tm_map

This patch replaces kstrtouint()'s patameter base with 0 in the
hclge_dbg_dump_tm_mac(), which makes it more flexible. Also
uses a macro to replace string "dump tm map", since it has been
used multiple times.
