bug#8260: which-function fails to find current function name

which-function fails to find the current function name if a major
mode adjusts add-log-current-defun-header-regexp but does not bind
add-log-current-defun-function.  Thus, which-function shall call
add-log-current-defun to query the current function name.  Below
is a patch together with a change log entry.

        * progmodes/which-func.el (which-function): Call add-log-current-defun
        instead of evaluating add-log-current-defun-function directly.
