gianfar: Do right check on num_txbdfree
This patch fixes a wrong check on num_txbdfree. It could lead to num_txbdfree become nagative. Result was that the gianfar stops sending data. Changes from first version : - removed a space between parens (David Millers comment) - full email address in signed off line Signed-off-by: Rini van Zetten <rini@arvoo.nl> Acked-by: Andy Fleming <afleming@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
