i40e: Warn admin to reload VF driver on port VLAN configuration
The i40e Physical Function (PF) driver will allow the
Virtual Function (VF) driver to configure its own VLAN filters if no port
VLAN filter has been configured. This leads to the possibility of the
administrator setting a port VLAN filter for the VF after the VF has already
configured its own VLAN filters. This leads to a conflict that can only be
resolved by reloading the VF driver. When the conflicting administrative
command is detected in setting the port VLAN then log a message indicating to
the system administrator that he must now reload the VF driver for the new
port VLAN settings to take effect.
