Stefan Raspl 65d8013cbd qeth: fix qeth_wait_for_threads() deadlock for OSN devices 
Any recovery thread will deadlock when calling qeth_wait_for_threads(), most
notably when triggering a recovery on an OSN device.
This patch will store the recovery thread's task pointer on recovery
invocation and check in qeth_wait_for_threads() respectively to avoid
deadlocks.
