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.
