mlx4_en: Fix cleanup if workqueue create in mlx4_en_add() fails
If creating a workqueue fails, don't jump to the error path where that same workqueue is destroyed, since destroy_workqueue() can't handle a NULL pointer. This was spotted by the Coverity checker (CID 2617). Signed-off-by: Roland Dreier <rolandd@cisco.com> Signed-off-by: David S. Miller <davem@davemloft.net>
