[RFC PATCH 2/3] ixgbe: Use default fdb handlers when not in VF mode.

[Vlad Yasevich <vyasevic@redhat.com>]

Allow the use of ndo_dflt_fdb_<add|del|dump> when the
adapter does not have VF configured.  This allows for
IFF_UNICAST_FLT support and allows VF handling to potentially
do something different.
