To eliminate the use of struct page in page pool, the page pool users
should use netmem descriptor and APIs instead.
Make fbnic access @pp through netmem_desc instead of page.
Signed-off-by: Byungchul Park <byungchul@sk.com>

Changes from rfc:
1. Use pp_page_to_nmdesc(page)->pp instead a wrong approach,
ring->page_pool. (feedbacked by Jakub)
