From: Yunsheng Lin <linyunsh...@huawei.com>
The HNS3_RXD_VLD_B bit has already been checked in hns3_add_frag
or hns3_handle_rx_bd before calling hns3_handle_bdinfo, so when
hns3_handle_bdinfo is called, the HNS3_RXD_VLD_B bit is always
set, which makes the checking in hns3_handle_bdinfo unnecessary.
This patch removes the RXD_VLD_B checking in hns3_handle_bdinfo.
