s3-printing: Fix double free of cups request.

s3-printing: Fix double free of cups request.

We never free the request in our cups api usage except for here. The reason is
probably htis (from the cupsDoConnect API docs):

"This function sends the IPP request to the specified server, retrying and
authenticating as necessary. The request is freed with ippDelete() after
receiving a valid IPP response."

Revert "Fix a memory leak in cups_pull_comment_location"

This reverts commit fee2664dad37536b05ce8bdae3e74d45b257f632.
