Subject: [PATCH net-next 6/9] net: hns3: Use enums instead of magic number in hclge_is_special_opcode

This patch does bit of a clean-up by using already defined enums for
certain values in function hclge_is_special_opcode(). Below enums from
have been used as replacements for magic values:

enum hclge_opcode_type{
	<snip>
	HCLGE_OPC_STATS_64_BIT		= 0x0030,
	HCLGE_OPC_STATS_32_BIT		= 0x0031,
	HCLGE_OPC_STATS_MAC		= 0x0032,
	<snip>
};
