[PATCH rdma-next] RDMA/cxgb4: Remove unnecessary conversion from __be32 to cpu format

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

The scqe.stag is actually declared in u32 format and don't need
conversion from __be32 to cpu format.

Remove the be32_to_cpu() and avoid the following sparse error.
  drivers/infiniband/hw/cxgb4/cq.c:754:52: warning: cast to restricted __be32
