[PATCH 5.7 053/120] net: hns3: fix for VLAN config when reset failed

[Greg Kroah-Hartman]

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

[ Upstream commit b7b5d25bdd7bdea7d72a41e0a97b1b8f3dea2ee7 ]

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")
