net: make page_pool_ref_netmem work with net iovs
page_pool_ref_netmem() should work with either netmem representation, but
currently it casts to a page with netmem_to_page(), which will fail with
net iovs. Use netmem_get_pp_ref_count_ref() instead.
Fixes: 8ab79ed50cf1 ("page_pool: devmem support")
