net sysfs: Print link speed as signed integer
Otherwise 4294967295 (MBit/s) (-1) will be printed when there is no link. Documentation/ABI/testing/sysfs-class-net does not state if this shall be signed or unsigned. Also remove the now unused variable fmt_udec. Signed-off-by: Alexander Stein <alexander.stein@systec-electronic.com> Signed-off-by: David S. Miller <davem@davemloft.net>
