Subject: [PATCH iwl-next v5 04/12] ice: Disable vlan pruning for uplink VSI

In switchdev mode, uplink VSI is configured to be default
VSI which means it will receive all unmatched packets.
In order to receive vlan packets we need to disable vlan pruning
as well. This is done by dis_rx_filtering vlan op.
