Subject: [PATCH] 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
