Jon Hunter 8f8e48f4d6 serial: tegra: Fix memory leak on DMA setup failure ...

If the call to dmaengine_slave_config() fails, then the DMA buffer will
not be freed/unmapped. Fix this by moving the code that stores the
address of the buffer in the tegra_uart_port structure to before the
call to dmaengine_slave_config().
