net/sfc: allow one Rx queue entry carry many packet buffers

One HW Rx descriptor has many packet buffers in the case of equal
stride super-buffer Rx modes. Each packet buffer is still treated
as separate SW Rx descriptor. rxq_entries is the size of HW Rx ring
whereas nb_rx_desc is the number of SW Rx descriptors.
