[Downloads] Update origin info after each response.
When a download is resumed, a new URL request is sent out. The response
received for this request may contain new ETag and Last-Modified
information which should be used for subsequent resumption attempts.
Otherwise if a resource changes (along with the corresponding ETag)
subsequent partial resumption attempts will all fail even if it should
have succeeded.
BUG=7648
