Subject: [PATCH net-next 02/12] net: hns3: Unify the type convert for desc.data

From: Jian Shen <shenjian15@...wei.com>

For desc.data is already point to the address of struct member "data[6]",
it's unnecessary to use '&' to get its address. This patch unifies all
the type convert for dest.data, using "req = (struct name *)dest.data".
