Subject: IB/mlx5: Remove set-but-not-used variables
Patch-mainline: v4.19-rc1
Git-commit: 7496a511a0be976406d0e7ab8cdec7df6e5aac04
References: bsc#1103991 FATE#326007

Avoid that the compiler complains about set-but-not-used variables when
building with W=1. This patch does not change any functionality.
