[PATCH AUTOSEL 5.2 87/94] net: aquantia: fix removal of vlan 0

[Sasha Levin]

From: Dmitry Bogdanov <dmitry.bogdanov@xxxxxxxxxxxx>

[ Upstream commit 6fdc060d7476ef73c8029b652d252c1a7b4de948 ]

Due to absence of checking against the rx flow rule when vlan 0 is being
removed, the other rule could be removed instead of the rule with vlan 0

Fixes: 7975d2aff5afb ("net: aquantia: add support of rx-vlan-filter offload")
