[PATCH net-next v2 4/4] page pool: Remove init_callback parameter

["Toke Høiland-Jørgensen" <toke@redhat.com>]

The only user of the init_callback parameter to page pool was the
BPF_TEST_RUN code. Since that has now been moved to use a different
scheme, we can get rid of the init callback entirely.
