MLK-17491-2 serial: fsl_lpuart: improve the baud setting algorithm

If "baud_diff == 0", it means we already found the exact matching baud
rate and no need try looping the left possible baud rates anymore.

So in this patch, we break out immediately once we find the right baud
rate to avoid the left meaningless loops.
