Subject: i40e: Remove rx page reuse double count
Patch-mainline: v5.18-rc1
Git-commit: 89bb09837b9719d54670420aa2edc9cf442194a8
References: jsc#PED-372
Page reuse was being tracked from two locations:
- i40e_reuse_rx_page (via 40e_clean_rx_irq), and
- i40e_alloc_mapped_page
Remove the double count and only count reuse from i40e_alloc_mapped_page
when the page is about to be reused.
