[PATCH net 5/5] net: hns3: fix for VLAN config when reset failed

[Huazhong Tan]

From: Guojia Liao <liaoguo...@huawei.com>

When device is resetting or reset failed, firmware is unable to
handle mailbox. VLAN should not be configured in this case.

Fixes: fe4144d47eef ("net: hns3: sync VLAN filter entries when kill VLAN ID 
failed")
