fcoe: consolidates netdev related config and cleanup for spma mode
Currently fcoe_netdev_config adds netdev pkt handler for fcoe pkts, fcoe_if_create adds netdev pkt handler for fip packets, a secondary MAC address is added by fcoe_netdev_config and then later cleanup for these netdev related config/adds is done only during fcoe_if_destroy and no cleanup done on error during fcoe interface creation after above netdev config calling in fcoe_if_create. So this patch adds single func for above mentioned cleanup the fcoe_netdev_cleanup and then calls this func on either fcoe interface destroy or exiting from fcoe_if_create due to an error after fcoe/fip related above netdev config is done. Moved netdev pkt handler addition code blocks for fip pkts close to similar code block for foce pkt in fcoe_netdev_config, so that added fcoe_netdev_cleanup could be called on error from fcoe_netdev_config to undo these both additions for fcoe/fip pkt handlers. This move required reference to fcoe_fip_recv in fcoe_netdev_config, so moved fip related functions fcoe_fip_recv, fcoe_fip_send and fcoe_update_src_mac above fcoe_netdev_config. This consolidation will enable spma mode support in next patch to easily add or delete spma mode mac address beside fixing current no cleanup issue during error.
