RDMA/ocrdma: Fix compiler warning about int/pointer size mismatch 

Fix:

   drivers/infiniband/hw/ocrdma/ocrdma_verbs.c: In function 'ocrdma_build_fr':
>> drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:1832:7: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
     mr = (struct ocrdma_mr *)qp->dev->stag_arr[(hdr->lkey >> 8) &
          ^
