locking/spinlock/debug: Remove spinlock lockup detection code
...
The current spinlock lockup detection code can sometimes produce false
positives because of the unfairness of the locking algorithm itself.
So the lockup detection code is now removed. Instead, we are relying
on the NMI watchdog to detect potential lockup. We won't have lockup
detection if the watchdog isn't running.
The commented-out read-write lock lockup detection code are also
removed.
