Subject: net/rds: Remove two WARN_ON() statements
Patch-mainline: v4.19-rc1
Git-commit: 197c782e3a18cc2de8766dc30a56f37b9b7a9eec
References: bsc#1103992 FATE#326009
Remove two WARN_ON() statements that verify something that is guaranteed
by the RDMA API, namely that the failed_wr pointer is not touched if an
ib_post_send() call succeeds and that it points at the failed wr if an
ib_post_send() call fails.
