workqueue: Avoid nr_active manipulation in grabbing inactive items
Current try_to_grab_pending() activates the inactive item and
subsequently treats it as though it were a standard activated item.
This approach prevents duplicating handling logic for both active and
inactive items, yet the premature activation of an inactive item
triggers trace_workqueue_activate_work(), yielding an unintended user
space visible side effect.
And the unnecessary increment of the nr_active, which is not a simple
counter now, followed by a counteracted decrement, is inefficient and
complicates the code.
Just remove the nr_active manipulation code in grabbing inactive items.
