net: hns3: fix the bug when reuse command description in hclge_add_mac_vlan_tbl

Browse source

When reusing a command description read from HW, driver should set
IN_VLD bit, WR bit and NO_INTR bit. If IN_VLD bit and NO_INTR bit
are not set, the command fails and driver prints error message:

[  135.261284] hns3 0000:7d:00.0: cmdq execute failed for get_mac_vlan_cmd_status,status=2.
[  135.270983] hns3 0000:7d:00.0: add mac addr failed for cmd_send, ret =-5.

This patch fixes the bug.
