kdb: Don't back trace on a cpu that didn't round up
[ Upstream commit 162bc7f5afd75b72acbe3c5f3488ef7e64a3fe36 ]
If you have a CPU that fails to round up and then run 'btc' you'll end
up crashing in kdb becaue we dereferenced NULL. Let's add a check.
It's wise to also set the task to NULL when leaving the debugger so
that if we fail to round up on a later entry into the debugger we
won't backtrace a stale task.
