[PATCH] RDMA/mlx5: Fix query_srq_cmd() function

[Dan Carpenter <dan.carpenter@oracle.com>]

The "srq_out" pointer is never freed so that causes a memory leak.  It's
never used and can be deleted.  Freeing "out" will lead to a double in
mlx5_ib_query_srq().

Fixes: 31578defe4eb ("RDMA/mlx5: Update mlx5_ib to use new cmd interface")
