serial: imx: only set dma_is_rxing when DMA starts
The variable dma_is_rxing is currently set to 1 in imx_disable_rx_int(). This is problematic as: - whilst imx_disable_rx_int() is currently always called before start_rx_dma() this dependency isn't obvious. - start_rx_dma() does error checking and might exit without enabling DMA. Currently this will result in dma_is_rxing suggesting that DMA is being used for recieving. To avoid these issues, move the setting of dma_is_rxing to start_rx_dma() when appropriate.
