X-Git-Tag: firefly_0821_release~7613^2~2505^2~1

RDMA/amso1100: Fix compile warnings

Fix compile warnings on 32-bit by using "0" instead of "(u64) NULL" to
assign to "c2_vq_req->reply_msg".

[ Change from "(unsigned long) NULL" to plain old "0" as suggested by
  Bart Van Assche <bvanassche@acm.org>.  - Roland ]
