Delete rx_desc_92d because it's big and barely used, and instead use the get_rx_desc_rxmcs and get_rx_desc_rxht functions, which work on big endian systems too. Fix rx_fwinfo_92d by duplicating four of its members in the correct order. Tested only with RTL8192DU, which will use the same code. Tested only on a little endian system.
