ide: sanitize ide_end_rq()
* Move 'uptodate' quirk from ide_end_rq() to its users. * Move quirks for blk_noretry_request() and !blk_fs_request() requests from ide_end_rq() to ide_end_request(). There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
