Superfluous comment inside `DebugToolbarMiddleware.__call__`

[rnazali]

The DebugToolbarMiddleware.__call__ method contains seemingly superfluous comments that might be simplified - tough may be trivial - for better readability.

django-debug-toolbar/debug_toolbar/middleware.py

Lines 128 to 133 in 0136ff9

	def __call__(self, request: HttpRequest) -> HttpResponse:
	# Decide whether the toolbar is active for this request.
	if self.async_mode:
	return self.__acall__(request)
	# Decide whether the toolbar is active for this request.
	show_toolbar = get_show_toolbar(async_mode=self.async_mode)

Considering that DebugToolbarMiddleware.__acall__ (the async one just beneath) also includes the same comment:

django-debug-toolbar/debug_toolbar/middleware.py

Lines 153 to 155 in 0136ff9

	async def __acall__(self, request: HttpRequest) -> HttpResponse:
	# Decide whether the toolbar is active for this request.
	show_toolbar = get_show_toolbar(async_mode=self.async_mode)

A change to something like this might be more concise:

    def __call__(self, request: HttpRequest) -> HttpResponse:
        # Decide whether the toolbar is active for this request.
        if self.async_mode:
            return self.__acall__(request)
        show_toolbar = get_show_toolbar(async_mode=self.async_mode)

I'm keen to creating a PR, but I would appreciate what others think before trying to revert something that may be intended in the first place for some reason.

The comment above if self.async_mode could be removed; I think leaving the two comments above the get_show_toolbar invocations is fine. On the other hand, get_show_toolbar is quite clear itself, so removing those comments altogether would be fine for me as well.
