Subject: RDMA/qedr: Missing error code in qedr_init_user_queue()
Patch-mainline: v4.15-rc1
Git-commit: 89fd2576cba4bacd1a1a8738313a913d4ca95855
References: bsc#1050545 FATE#322893

We should return -ENOMEM if the kzalloc() fails.  We currently return
success.

Fixes: 69ad0e7fe845 ("RDMA/qedr: Add support for iWARP in user space")
