file-remote-p has been introduced with Emacs 22. XEmacs has it for a
while (I don't know since when).
For Emacs 21, file-remote-p is defined in tramp-util.el. Unfortunately,
this package was not loaded on Windows machines. This has been fixed
in CVS some weeks ago; will be released with Tramp 2.1.7. As
workaround you might use the code from there:
;;; emacs does not have file-remote-p, but it's apparently required by tramp
(if (not (fboundp 'file-remote-p))
;; Emacs 21
(defalias 'file-remote-p (symbol-function 'tramp-handle-file-remote-p)))

I don't believe that's the solution. localname is defined in order to
satisfy the byte-compiler; it is defined again inside the macro
with-parsed-tramp-file-name, and the value from there is used.
Your solution uses bfn, which is a remote file. This doesn't make
sense - the parameter FILE of tramp-flush-file-property is intended to
be a local file name.
Could you, please, give me a recipe how you were "not able to M-x
revert-file"? What's the buffer where you have called revert-file?
What's the buffer-file-name from that buffer?
Best regards, Michael.
