iw_cxgb3 has a potential problem wherein the cq's comp_handler

callback per CQ should be active.
Such problem was reported by Parav Pandit<[email protected]> for
iw_cxgb4 driver. Based on discussion between Parav Pandit and Steve Wise,
this patch aims to correct above problem by serializing the calls to cq's
comp_handler using a spin_lock.
