RDMA/cxgb3: MEM_MGT_EXTENSIONS support
- set IB_DEVICE_MEM_MGT_EXTENSIONS capability bit if fw supports it. - set max_fast_reg_page_list_len device attribute. - add iwch_alloc_fast_reg_mr function. - add iwch_alloc_fastreg_pbl - add iwch_free_fastreg_pbl - adjust the WQ depth for kernel mode work queues to account for fastreg possibly taking 2 WR slots. - add fastreg_mr work request support. - add local_inv work request support. - add send_with_inv and send_with_se_inv work request support. - removed useless duplicate enums/defines for TPT/MW/MR stuff.
