bug#24904: 25.1; whitespace-mode ignores file- and dir-locals

whitespace-mode seems to ignore file- and dir-locals when enabled
via `global-whitespace-mode`.

To reproduce:

1. Create a file with the following contents (use everything between the
   dashes, the dashes themselves are not part of the file):
-----------------------------test-file.txt--------------------------------------
Only open this file after global-whitespace-mode was enabled.

This is where highlighting of the line should start if everyhing went as
expected: right here  ---->|<----
However, if whitespace-mode incorrectly used the default of 80: right here
---->|<----

;; Local Variables:
;; whitespace-line-column: 100
;; End:
--------------------------------------------------------------------------------

Then:

2. Run `emacs -Q`

3. Execute the following commands from the scratch buffer:

(setq whitespace-style '(face lines-tail))
(global-whitespace-mode)

4. Open the created file using `M-x find-file test-file.txt`

whitespace-mode will highlight long lines starting at 80 characters
instead of 100, which is what the file-local variable says.

If whitespace-mode is enabled locally, after the file-local variables
are set, everything works as expected.

The same issue is explained here:
http://emacs.stackexchange.com/questions/7743/whitespace-mode-ignores-whitespace-line-column

I'm merely referring it to this bugtracker.

(This bug report unfortunately got no response at the time.)

I'm unable to reproduce this in Emacs 26.1 and Emacs 28.  Are you still
seeing this problem in more recent Emacs versions?

just tested again with my current setup of 26.1 and indeed it seems the
issue is resolved.
