I think simply calling `fill-paragraph' (bound to "M-q" by default)
should do. From it's docstring, it should take care about mode-specific
fill functions:

Also, the docstring says that fill-paragraph-function is expected to
return non-nil when the filling is done there. For some reason, it is
not done in org-fill-paragraph.

The attached is patch solving the "M-q" problem and making sure the
org-fill-paragraph returns non-nil.

Beware that I am not very familiar with fill.el. It would be great if
someone more knowledgeable take a look at the patch.

Best,
