    exynos5420: i2c: Fix error handling.
    
    The functions which checked the status of a transfer would return success if
    the bus was no longer occupied, even if it's no longer occupied because the
    transfer failed. This change modifies those functions to return three possible
    values, 0 if the transfer isn't done, -1 if there was a fault, and 1 if the
    transaction completed successfully.
