Subject: net: hns3: remove redundant memset when alloc buffer
Patch-mainline: v4.15-rc1
Git-commit: 51145dae2748233315a7a411cd97f4bedf8cc22f
References: bsc#1104353 FATE#326415
HW will use packet length to write packets to buffer or read
packets from buffer. There is a redundant memset when alloc buffer,
the memset have no sense and will increase time-consuming.
This patch removes it.
