[PATCH] net/bonding: fix destroy dedicated queues flow

[Chaoyong He]

From: Long Wu <long.wu at corigine.com>

Bonding port in mode 4 enables dedicated queues, we
will create a flow for this feature. So we need to
destroy this flow when we remove the member port.

Furthermore if we don't destroy the flow that created
for dedicated queues when we remove the member port,
maybe we couldn't add the member port to a new bonding
port that needed dedicated queues.

We add the destroy action in removing member port
function.

Fixes: 49dad9028e2a ("net/bonding: support flow API")
