rerere: fix comment on handle_file() helper

The return value from handle_path() is returned to the caller of
handle_file() in the normal cases, and it is not the number of
hunks. It is just a normal C Boolean, "do we (!=0) or do we not (0)
have conflict?" plus "a negative return value signals an error".

And all the callers of handle_file() understands its return value as
such.  Update the comment to match the reality after 221444f5
(rerere: only return whether a path has conflicts or not,
2018-08-05), which apparently forgot to update this comment when it
turned the returned value of this function from the number of
conflict hunks to a boolean plus error.
