Subject: [PATCH 4.9 153/177] RDMA/cma: Use correct size when writing netlink stats

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Parav Pandit <parav@...lanox.com>


[ Upstream commit 7baaa49af3716fb31877c61f59b74d029ce15b75 ]

The code was using the src size when formatting the dst. They are almost
certainly the same value but it reads wrong.
