http-fetch: Abort requests for objects which arrived in packs

Browse Source 
In fetch_object, there's a call to release an object request if the
object mysteriously arrived, say in a pack.  Unfortunately, the fetch
attempt for this object might already be in progress, and we'll leak the
descriptor.  Instead, try to tidy away the request.
