Subject: RDMA/mlx4: Fix create qp command alignment
Patch-mainline: v4.14-rc1
Git-commit: 55f2467cd717241dd941153d4db1e23c91aecf98
References: bsc#1046302 FATE#322945
Avoid extra padding by replacing the order of inl_recv_sz and reserved,
otherwise 'mlx4_ib_create_qp' structure might be larger than legacy user
input leading to copy of some garbage data from the user space buffer.
Fixes: ea30b966f7dd ('IB/mlx4: Add inline-receive support')
