Perfect FDIR filters can be added while the interface is down and are
kept on the software list for later restore. unregister_netdev() only
calls ndo_stop when the device is up, so txgbe_fdir_filter_exit() in
txgbe_close() is skipped in that case and the filters are leaked on
driver remove. Free the filter list from txgbe_remove() as well.
