[Intel-wired-lan] [PATCH net] ice: fix enabling RX VLAN filtering

[Petr Oros]

ice_port_vlan_on/off() was introduced in commit 2946204b3fa8 ("ice:
implement bridge port vlan"). But ice_port_vlan_on() incorrectly assigns
ena_rx_filtering to inner_vlan_ops in DVM mode.
This causes an error when rx_filtering cannot be enabled in legacy mode.

Reproducer:
 echo 1 > /sys/class/net/$PF/device/sriov_numvfs
 ip link set $PF vf 0 spoofchk off trust on vlan 3
dmesg:
 ice 0000:41:00.0: failed to enable Rx VLAN filtering for VF 0 VSI 9 during VF 
rebuild, error -95

Fixes: 2946204b3fa8 ("ice: implement bridge port vlan")
