Li Zefan a6572f84c5 watchdog: Disallow setting watchdog_thresh to -1 ...

In old kernels, it's allowed to set softlockup_thresh to -1 or 0
to disable softlockup detection. However watchdog_thresh only
uses 0 to disable detection, and setting it to -1 just froze my
box and nothing I can do but reboot.
