This patch introduces a dedicated workqueue for irq injection
so that we are able to do some performance tuning for it.

If we want the split like this.

It might be better to:

1) implement a simple irq injection on the ioctl context in patch 8
2) add the dedicated workqueue injection in this patch

Since my understanding is that

1) the function looks more isolated for readers
2) the difference between sysctl vs workqueue should be more obvious
than system wq vs dedicated wq
3) a chance to describe why workqueue is needed in the commit log in
this patch

OK, I will try to do it in v4.

Thanks,
Yongji
