Subject: [RFC PATCH 3/3] mlx4: Use default fdb handlers when not multifunction.

Allow the use of ndo_dflt_fdb_<add|del|dump> when the
adapter is not configured with virtual functins (!mlx4_is_mfunc())
This allows proper IFF_UNICAST_FLT support and allows for
additional handling by the driver if needed.
