net: airoha: Get rid of dma_sync_single_for_device() in airoha_qdma_fill_rx_queue()

Browse Source 
Since the page_pool for airoha_eth driver is created with
PP_FLAG_DMA_SYNC_DEV flag, we do not need to sync_for_device each page
received from the pool since it is already done by the page_pool codebase.
