Alexander Lobakin 782dbbf589 netdev_features: convert NETIF_F_FCOE_MTU to dev->fcoe_mtu 
Ability to handle maximum FCoE frames of 2158 bytes can never be changed
and thus more of an attribute, not a toggleable feature.
Move it from netdev_features_t to "cold" priv flags (bitfield bool) and
free yet another feature bit.
