DOWNLOAD_FAIL_ON_DATALOSS logged for all requests

[Gallaecio]

[scrapy.core.downloader.handlers.http11] Got data loss in . If you want to process broken responses set the setting DOWNLOAD_FAIL_ON_DATALOSS = False -- This message won't be shown in further requests

This message is logged every time you get data loss on a request.

I’ve had a quick look at the code, and it figures, since the flag to avoid repeating the message is stored on a _ResponseReader instance, and for each response a new _ResponseReader instance is created.

Relates to #2590 (original implementation).

Hi @Gallaecio, I'm a newcomer and I would like to give a try on this.

Go ahead. Although I’m note sure it is best suited for a newcomer; don’t feel bad it seems overwhelming, the affected parts of code are rather complex, it may take some code reading.
