[Intel-wired-lan] [PATCH net-next v3 3/9] igc: Refactor igc_clean_rx_ring()

From: Andre Guedes <andre.guedes at intel.com>
Refactor igc_clean_rx_ring() helper, preparing the code for AF_XDP
zero-copy support which is added by upcoming patches.
The refactor consists of encapsulating page-shared specific code into
its own helper, leaving common code that will be shared by both
page-shared and xsk pool in igc_clean_rx_ring().
