block: don't return 1 for the fallback case in blkdev_get_zone_info

blkdev_do_report_zones returns the number of reported zones, but blkdev_get_zone_info returns 0 or an errno. Translate to the expected return value in blkdev_report_zone_fallback.

Doh! Of course...

Note: Is this patch alone or part of a series ? (the subject has the odd 3/2...)

Yeah, this was supposed to be a follow up to the report zones caching fixes, but I edited out the in-reply-to header accidentally.

Applied, thanks!
