etheriwl: don't break controller on command flush timeout

ori and echoline are reporting regression on some 6000 cards;
which sometimes time out on crystal calibration command;
which is expected by the driver. but the new code used
to force a device reset on any command timeout.

reverting to old behaviour until for now until we have
a chance investigating.
