      Optimize cxgb3 xmit path (a bit) · a8cc21f6

      	1. Add common code for stopping queue.
      	2. No need to call netif_stop_queue followed by netif_wake_queue (and
      	   infact a netif_start_queue could have been used instead), instead
      	   call stop_queue if required, and remove code under USE_GTS macro.
      	3. There is no need to check for netif_queue_stopped, as the network
      	   core guarantees that for us (I am sure every driver could remove
      	   that check, eg e1000 - I have tested that path a few billion times
      	   with about a few hundred thousand qstops but the condition never
      	   hit even once).
