[misc] fix conversion of windows error codes

Browse source 
* Commit f453dc272b improved on error message reporting, but went a bit
  too far in trying to let Windows facilities sort their messages out.
* Add a retry that clears the facility, so that, for one thing, we get wininet
  messages properly processed, regardless of the official facility assigned.
