RDMA/mlx4: Fix create qp command alignment
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')
