avg 74e5eef4ea unconditionally stop other cpus when entering kdb in smp system
... and thus retire debug.kdb.stop_cpus tunable/sysctl.

either fixed or greatly reduced.  kdb should really operate in a special
environment with scheduler stopped and interrupts disabled to provide
deterministic debugging.
