sfc: Accumulate RX_NODESC_DROP count in rx_dropped, not rx_over_errors

rx_over_errors appears to be intended as a count of packets that
overflow a packet buffer in the NIC.  Given that we implement a
cut-through receive path, this should always be 0.

rx_dropped appears to be the correct counter for packets dropped due
to lack of host buffers.
