[SCSI] fcoe: Call ndo_fcoe_enable/disable to turn FCoE feature on/off in LLD 



Calls ndo_fcoe_enabled() of the associated netdev upon creating the FCoE
instance to make sure LLD has all necessary resources allocated and setup
properly before passing FCoE traffic. Similarly, calls ndo_fcoe_disable()
upon destroying the FCoE instance on the associated netdev to allow the LLD
to release all allocated resources for FCoE.
