RDMA/cxgb3: Set the max_qp_init_rd_atom attribute in query_device
The device attribute max_qp_init_rd_atom is not getting set in cxgb3's query_device method. Version 1.0.4 of librdmacm now validates the user's requested initiator and responder resources against the max supported by the device. Since iw_cxgb3 wasn't setting this attribute (and it defaulted to 0), all rdma_connect()s fail if there are initiator resources requested by the app. Fix this by setting the correct value in iwch_query_device().
