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
