Subject: IB: Ensure that all rdma_ah_attr's are zero initialized
Patch-mainline: v4.19-rc1
Git-commit: fb51eecaa523c909cdc6240d3e9b8bfc74e7a888
References: bsc#1103992 FATE#326009
Since we are adding some new fields to this structure it is safest if all
users reliably initialize the struct to zero.
