[ofw] [PATCH] mlx4u.dll: initialize QP pointer before use

[Sean Hefty]

We need to initialize the qp pointer to NULL to avoid accessing some random
memory location when polling for completions.  Without this, calls to
mlx4_poll_cq_array() can crash in mlx4_poll_one().

A bonus patch!  To make it easier, I can commit this when committing the
rdma cm support.
