i2c: Add asserts for second smbus i2c_start_transfer()
...
Some SMBus operations restart the transfer to convert from
write to read mode without an intervening i2c_end_transfer().
The second call cannot fail, so the return code is unchecked,
but this causes Coverity to complain. So add some asserts
and documentation about this.
