Rework network interface logic. Before this change, the code flow was: 1. Disable interrupt 2. Try to schedule a NAPI 3. Check if it was possible (NAPI is not already scheduled) 4. emit BUG() if we receive interrupt while a NAPI is scheduled If some application busy poll or set gro_flush_timeout low enough, it's possible to reach the BUG() condition. Given that the condition may happen and it wouldn't be a bug, rework the logic to permit such case and prevent stall with interrupt never enabled again. Disable the interrupt only if the NAPI can be scheduled (aka it's not already scheduled) and drop the printk and BUG() call. With these change, in the event of a NAPI already scheduled, the interrupt is simply ignored with nothing done.
