net/mlx5e: Optimize the page cache reducing its size 2x
RX page cache stores dma_info structs, that consist of a pointer to struct page and a DMA address. In fact, the DMA address is extracted from struct page using page_pool_get_dma_addr when a page is pushed to the cache. By moving this call to the point when a page is popped from the cache, we can avoid storing the DMA address in the cache, effectively reducing its size by two times without losing any functionality.
