target: simply fabric driver queue full processing
There is no need to schedule the delayed processing in a workqueue that
offloads it to the target processing thread. Instead execute it directly
from the workqueue. There will be a lot of future work in this area,
which I'd likfe to defer for now as it is not nessecary for getting rid
of the target processing thread.
