net/cxgbe: remove rmb bottleneck in Rx path

rmb before determining rsp_type is a bottleneck.
Once we determine rsp-type is FL, we can directly go ahead and read
packets based on q->stat->pidx and budget_left.

This removes bottleneck of rmb once per every RX packet.
Now, rmb exists once per RX batch.
