i2c: i2c-tegra: Return error code on partial master_xfer transfer

It is unclear what the correct return value is when
master_xfer gets an error part way through a set of
messages, but other drivers seem to return the error
code of the individual failed message instead of
the number of successful messages.  Convert the Tegra
i2c driver to do the same.
