net: Revert the softirq will run annotation in ____napi_schedule().
The lockdep annotation lockdep_assert_softirq_will_run() expects that either hard or soft interrupts are disabled because both guaranty that the "raised" soft-interrupts will be processed once the context is left. This triggers in flush_smp_call_function_from_idle() but it this case it explicitly calls do_softirq() in case of pending softirqs. Revert the "softirq will run" annotation in ____napi_schedule() and move the check back to __netif_rx() as it was. Keep the IRQ-off assert in ____napi_schedule() because this is always required.
