net: ethernet: mlx4: Avoid assigning a value to ring_cons but not used it anymore in mlx4_en_xmit()
We found a set but not used variable 'ring_cons' in mlx4_en_xmit(), it will cause a warning when build the kernel. And after checking the commit record of this function, we found that it was introduced by a previous patch. So, We delete this redundant assignment code. Fixes: 488a9b48e398 ("net/mlx4_en: Wake TX queues only when there's enough room") Signed-off-by: Luo Jiaxing <luojiaxing@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
