You have to use backquotes so that expressions are considered as code to
execute, instead of data. See Emacs manual.

In your case, something like this should do it (untested):

#+begin_src emacs-lisp
(setq org-capture-templates
 `(("m" "Message" entry (file+datetree
   ,(buffer-file-name (buffer-base-buffer))) "* MSG @ %U %?\n %a")))
#+end_src

See backquote used instead of quote.
See comma in front of functions and variables.

Here, though, I'm not sure whether another comma is needed or not in front of
=buffer-base-buffer=.

Best regards,
  Seb
