lib: spinlock: Cause a watchdog bite on spin_dump
Currently we cause a BUG_ON once a spin_bug is detected, but
that causes a whole lot of processing and the other CPUs would
have proceeded to perform other actions and the state of the system
is moved by the time we can analyze it.
Provide an option to trigger a watchdog bite instead so that we
can get the traces as close to the issue as possible.
