forget: show warning messages for forgetting in subrepo correctly

in 'cmdutil.forget()':

   for f in match.files():
       if match.exact(f) or not explicitonly:
           ....

is equal to:

   for f in match.files():
       if True:
           ....

because 'f' from 'match.files()' should 'match.exact(f)':

    - 'match.files()' returns 'self._files'
    - 'match.exact(f)' examines 'f in self._fmap',
    - 'self._fmap' of match is 'set(self._files)'

then, 'explicitonly' wants to suppress warning messges, if it is true
(= 'cmdutil.forget()' is invoked from 'subrepo.forget()').

so, current code should be fixed as:

    if not explicitonly:
        for f in match.files():
           ....
