i40e: revert internal switch of PF

Browse Source 
VEB switching is blocking VF.
If the source mac address of packet sent from VF is not listed in the
VEB’s mac table, the VEB will switch the packet back to the VF.
It's an hardware issue.

Reverts: 2ccabd8cd1 ("i40e: enable internal switch of PF").
