Subject: [PATCH 4.19 563/639] RDMA/cma: Fix false error message

From: Håkon Bugge <haakon.bugge@...cle.com>

[ Upstream commit a6e4d254c19b541a58caced322111084b27a7788 ]

In addr_handler(), assuming status == 0 and the device already has been
acquired (id_priv->cma_dev != NULL), we get the following incorrect
"error" message:

RDMA CM: ADDR_ERROR: failed to resolve IP. status 0

Fixes: 498683c6a7ee ("IB/cma: Add debug messages to error flows")
