Don't call debug on failed cl-assert

Doing this causes problems when running ert tests, for
instance (Bug#24778).  The call to `debug` when `debug-on-error' is
non-nil was introduced in 2015-02-14 "* lisp/emacs-lisp/cl*.el: Use
define-inline and move some code...".

* lisp/emacs-lisp/cl-preloaded.el (cl--assertion-failed): Don't call
`debug' directly.
