ixgbe: FCoE: Add support for ndo_get_fcoe_hbainfo() call

Browse source 
This patch implements support for ndo_get_fcoe_hbainfo()
call in the ixgbe driver.

This function will be called by the FCoE protocol stack to
obtain device specific information from the underlying
device configured to do FCoE.
