i40e: enable fdb add code, remove unused code
The original FDB code submission wasn't correct and the code wasn't enabled. This removes some dead code (can use the common kernel code for fdb_del and fdb_dump) and correctly enables the fdb_add function pointer. The fdb_add functionality is important to i40e because it is needed for a workaround to allow bridges to work correctly on the i40e hardware.
