e1000e: Combine rx traces

Whether a packet will be written back to the guest depends on the
remaining space of the queue. Therefore, e1000e_rx_written_to_guest and
e1000e_rx_not_written_to_guest should log the index of the queue instead
of generated interrupts. This also removes the need of
e1000e_rx_rss_dispatched_to_queue, which logs the queue index.
