qeth: avoid recovery during device online setting
If a qeth device is set online, several initialisation steps are
performed. If a failure in one of these steps occurs, the qeth
device is reset into DOWN state. If due to the failure a qeth recovery
is scheduled and started in another thread, this might cause all kinds
of conflicts, even a kernel panic. The patch forbids scheduling of a
qeth recovery while online processing is performed till the card is in
state SOFTSETUP.
