r8169: improve handling task scheduling
If we know that the task is going to be a no-op, don't even schedule it.
And remove the check for netif_running() in the worker function, the
check for flag RTL_FLAG_TASK_ENABLED is sufficient. Note that we can't
remove the check for flag RTL_FLAG_TASK_ENABLED in the worker function
because we have no guarantee when it will be executed.
