The Tegra serial driver always prints an error message when enabling the FIFO for devices that have support for checking the FIFO enable status. Fix this by displaying the error message, only when an error occurs.
Finally, update the error message to make it clear that enabling the FIFO failed and display the error code.

Sorry, but it is not clear to me why this would be necessary in this case.
I see so '%pe' prints the symbolic name of the error code. While that is nice, it also looks a bit odd. Given that we simply print the error code values in this driver, from looking at other prints, I prefer to keep it as is for consistency.
