s390/qeth: send IDX cmds via qeth_send_control_data()
This converts the IDX code to use qeth_send_control_data(), replacing a bunch of duplicated IO code and unbounded waits. It also allows the IDX sequence to benefit from the improved timeout & notify infrastructure, so that we can eliminate the DOWN -> ACTIVATING -> UP transition in the channel state machine. The patch looks rather big, but most of it is a straight-forward conversion of the old IDX cmd setup & callbacks to the new model. Signed-off-by:Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by:
