bundle: remove obsolete (and duplicate) comment

Change 1e28ec9744bf (changegroup: move chunk extraction into a
getchunks method of unbundle10, 2014-04-10) extracted some code to a
getchunks() method and copied a comment about the changegroup format
to the new method. The copy that remains in the old place, doesn't
make much sense there, so let's remove it.
