[PATCH v4] seq_file: reset iterator to first record for zero offset

will not return iterator as position is already on the second object. This defect doesn't allow to monitor badblocks sysfs files from MD raid. They are initially empty but if data appears at some stage, userspace is not able to read it. Signed-off-by: Tomasz Majchrzak <tomasz.majchr...@intel.
