net: airoha: Set REG_RX_CPU_IDX() once in airoha_qdma_fill_rx_queue()

Browse source

It is not necessary to update REG_RX_CPU_IDX register for each iteration
of the descriptor loop in airoha_qdma_fill_rx_queue routine.
Move REG_RX_CPU_IDX configuration out of the descriptor loop and rely on
the last queue head value updated in the descriptor loop.
