page_pool: make page_pool_get_dma_addr() just wrap page_pool_get_dma_addr_netmem()
The page pool members in struct page cannot be removed unless it's not
allowed to access any of them via struct page.
Do not access 'page->dma_addr' directly in page_pool_get_dma_addr() but
just wrap page_pool_get_dma_addr_netmem() safely.
