Subject: net/smc: Remove a WARN_ON() statement
Git-commit: 12c36dcfd6f48ece2fce4dc8e6ce68224d005d37
Patch-mainline: v4.19-rc1
References: FATE#325694, LTC#167874, bsc#1113508

Remove a WARN_ON() statement that verifies 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.
