Subject: RDMA/qedr: Zero stack memory before copying to user space
Patch-mainline: v4.17-rc1
Git-commit: 57939021e8f882d13a5263a9d682c64ae00c578d
References: bsc#1086314 FATE#324886 bsc#1086313 FATE#324885 bsc#1086301 FATE#3248881

The fact this struct was not init'd like all the others was missed when
the padding reserved field was added.
