tty: serial: imx: use the sg count from dma_map_sg
commit 596fd8dffb745afcebc0ec6968e17fe29f02044c upstream.
The dmaengine_prep_slave_sg needs to use sg count returned
by dma_map_sg, not use sport->dma_tx_nents, because the return
value of dma_map_sg is not always same with "nents".
Fixes: b4cdc8f61beb ("serial: imx: add DMA support for imx6q")
