net/qede: fix filtering code

In qede_mac_addr_add() a check is added to differentiate between
unicast/multicast mac to prevent a multicast mac from being wrongly added
to unicast filter table. Secondly, two separate lists will be used to keep
track of unicast/multicast mac filters to prevent duplicate filter
programming. The other change is to remove filter_config from struct
qed_eth_ops_pass and invoke the base APIs directly. This avoids the need
to have multiple structs and function calls.
