Subject: [PATCH AUTOSEL 4.9 55/98] rds: ib: Fix missing call to rds_ib_dev_put in rds_ib_setup_qp

From: Dag Moxnes <dag.moxnes@...cle.com>

[ Upstream commit 91a825290ca4eae88603bc811bf74a45f94a3f46 ]

The function rds_ib_setup_qp is calling rds_ib_get_client_data and
should correspondingly call rds_ib_dev_put. This call was lost in
the non-error path with the introduction of error handling done in
commit 3b12f73a5c29 ("rds: ib: add error handle")
