[PATCH 2/2] app/testpmd: remove fast free offload for bond3 and bond4

[Huisong Li]

The port configurations of bonding device need to be updated when add a
slave device. But mbuf fast free offload can't be used in bonding mode
Broadcast and mode 8023AD. So remove this offload for both mode in case
of failing to initialize bonding device.

Fixes: 76376bd9cd49 ("app/testpmd: update bond port configurations when add slave")
