remove stop_scheduler_on_panic knob

There has not been any complaints about the default behavior, so there
is no need to keep a knob that enables the worse alternative.

Now that the hard-stopping of other CPUs is the only behavior, the panic_cpu
spinlock-like logic can be dropped, because only a single CPU is
supposed to win stop_cpus_hard(other_cpus) race and proceed past that
call.
