serial: pch_uart: Pass correct sg to dma_unmap_sg()
A local variable sg is used to store scatterlist pointer in
pch_dma_tx_complete(). The for loop doing Tx byte accounting before
dma_unmap_sg() alters sg in its increment statement. Therefore, the
pointer passed into dma_unmap_sg() won't match to the one given to
dma_map_sg().
To fix the problem, use priv->sg_tx_p directly in dma_unmap_sg()
instead of the local variable.
