s390/qeth: propagate length of processed cmd IO data to callback
When an cmd IO completes in qeth_irq(), calculate how much data was processed by the device and pass this value to the cmd's callback. This allows cmds that retrieve data from the device to check whether sufficient data was received, so we do that in qeth_read_conf_data_cb().
