serial: sirf: correct condition for fetching dma buffer into tty
In rx dma-callback it calls tasklet_schedule, if the tasklet
be scheduled after all the dma-callback in the rx dma channel,
current check condition in the tasklet will not do fetch dma
buffer into tty because tx_issued is equal with tx_completed,
so as timeout tasklet does.
so we check whether we should fetch the whole dma buffer into
tty according to the status of transactions in rx dma channel.
