[PATCH 4.19 22/56] rds: memory leak in __rds_conn_create()

[Greg Kroah-Hartman]

From: Hangyu Hua <hbh25y@xxxxxxxxx>

[ Upstream commit 5f9562ebe710c307adc5f666bf1a2162ee7977c0 ]

__rds_conn_create() did not release conn->c_path when loop_trans != 0 and
trans->t_prefer_loopback != 0 and is_outgoing == 0.

Fixes: aced3ce57cd3 ("RDS tcp loopback connection can hang")
