workqueue: add cmdline parameter workqueue.panic_on_stall
When we want to debug the workqueue stall, we can immediately make
a panic to get the information we want.
In some systems, it may be necessary to quickly reboot the system to
escape from a workqueue lockup situation. In this case, we can control
the number of stall detections to generate panic.
workqueue.panic_on_stall sets the number times of the stall to trigger
panic. 0 disables the panic on stall.
