[PATCH net-next v11 04/12] netdevsim: access ->pp through netmem_desc instead of page

[Byungchul Park <byungchul@sk.com>]

To eliminate the use of struct page in page pool, the page pool users
should use netmem descriptor and APIs instead.

Make netdevsim access ->pp through netmem_desc instead of page.
