Subject: [PATCH][next] RDMA/mlx5: remove duplicated assignment to resp.response_length

From: Colin Ian King <colin.king@...onical.com>

The assignment to resp.response_length is never read since it is being
updated again on the next statement. The assignment is redundant so
removed it.

Addresses-Coverity: ("Unused value")
