Peter Grehan c0498352c1 In stack_save, stop when a trap-frame is encountered. This prevents
trying to access user-space stack addresses when a user fault
is encountered, as occurs when GEOM KTR code is handling a page fault
and is using stack_save() to capture a trace for debug purposes.

It may be possible to walk beyond the trap-frame if it is a kernel fault,
as db_backtrace() does, but I don't think that complexity is needed in
this routine.
