bug#55678: 29.0.50; C-c C-w and errors in major-mode-hook

[Visuwesh]

I have paredit-mode in emacs-lisp-mode-hook, and when the buffer has
mismatched parens [(check-paren)=nil], it signals an error.  This makes
`diff-add-log-current-entries' not add any of the entries.

For a simple reproducer,

    1. emacs -Q
   
    2. M-: (add-hook 'emacs-lisp-mode-hook (defun test () (error "test error")))

    3. Create a temporary git repo, commit an initial change by adding
       an elisp file.

    4. Add some more text.  C-x v v.

    5. C-c C-w.  Note "test error" in the echo-area.

I narrowed down the problem to `diff-add-log-current-entries' and I
*think* the problem is in goto-otherbuf function but when I added an
ignore-error around (funcall (buffer-local-value 'major-mode buf)), I
noticed no change.  :-/

I can work around my specific problem but it would be nice if this was
handled in a generic way.
