[PATCH] RDMA/core: Fix error code in stat_get_doit_qp()

[PATCH] RDMA/core: Fix error code in stat_get_doit_qp()

[Dan Carpenter]

We need to set the error codes on these paths.  Currently the only
possible error code is -EMSGSIZE so that's what the patch uses.

Fixes: 83c2c1fcbd08 ("RDMA/nldev: Allow get counter mode through RDMA netlink")
