gpio: tpic2810: Make sure cached buffer has consistent status with h/w status
i2c_smbus_write_byte_data() can fail. To ensure the
cached buffer has consistent status with h/w status, don't
update the cached gpio->buffer if write fails.
Also refactor the code a bit by adding a tpic2810_set_mask_bits()
helper and use it to simplify the code.
