[PATCH net-next 6/7] net: hns3: remove redundant memset when alloc buffer

[Lipeng]

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.

Fixes: 76ad4f0 (net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC)
