net: stmmac: Set dma_sync_size to zero for discarded frames
If a frame is going to be discarded by driver, this frame is never touched
by driver and the cache lines never become dirty obviously,
page_pool_recycle_direct() wastes CPU cycles on unnecessary calling of
page_pool_dma_sync_for_device() to sync entire frame.
page_pool_put_page() with sync_size setting to 0 is the proper method.
