    kern: fix auditing of ptrace(2) syscall requests
    
    `error` here is the return value of syscall_thread_enter() rather than
    the syscall itself, so the committed audit records do not reflect
    reality.  This is less harmful than them recording an error when the
    operation actually succeeded, but it could still possibly be used to
    throw off IDS techniques with things like bsmtrace.
