1511 o correctly extends the timeout depending on the size of all
1512 queued messages for both transmit and receive
1513 o will not continue with receive if transmit times out
1514 o ensures that the error callback is done for all queued tx

1517 the callback, and does not overwrite an earlier error
1518 o logic in i2c_probe now correct
