nvethernet: Indicate more Rx frames pending

Browse Source 
Issue: The function osi_process_rx_completions does
       not provide indication whether there are more
       Rx frames in the HW ring to be processed by SW.
       This indication is needed in OSD layers like
       AUTOSAR MCAL driver as per the spec.
Fix:   Add more rx data flag arg to osi_process_rx_completions() call
