Subject: [PATCH net v3 0/1] i40e: xsk: advance next_to_clean on status descriptors

Hello,

As suggested by Maciej, submitting v3 which makes i40e_clean_rx_irq and
i40e_clean_rx_irq_zc use similar logic and a shared function
i40e_inc_ntp_ntc() to advance next_to_process and next_to_clean when
handling status descriptors. 

I've left the rest of the i40e_clean_rx_irq logic unchanged or this
patch would snowball. I think it'd be nice to change the function to
work with local variables and update the rx_ring only at the end like
_zc, but seems out of scope for this patch. 

Changes since v2:
 * use common utility function i40e_inc_ntp_ntc to advance indexes
