[PATCH 3.18 42/47] RDMA/cma: Use correct size when writing netlink stats

[Greg Kroah-Hartman]

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

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

From: Parav Pandit <parav@xxxxxxxxxxxx>


[ 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.

Fixes: ce117ffac2e9 ("RDMA/cma: Export AF_IB statistics")
