net/mlx5: HWS, check the correct variable in hws_send_ring_alloc_sq()
There is a copy and paste bug so this code checks "sq->dep_wqe" where "sq->wr_priv" was intended. It could result in a NULL pointer dereference. Fixes: 2ca62599aa0b ("net/mlx5: HWS, added send engine and context handling") Signed-off-by: Dan Carpenter <dan.carpenter@linaro.org> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://patch.msgid.link/da822315-02b7-4f5b-9c86-0d5176c5069d@stanley.mountain Signed-off-by: Jakub Kicinski <kuba@kernel.org>
