UBI: fastmap: scrub PEB when bitflips are detected in a free PEB EC header
commit ecbfa8eabae9cd73522d1d3d15869703c263d859 upstream.
scan_pool() does not mark the PEB for scrubing when bitflips are
detected in the EC header of a free PEB (VID header region left to
0xff).
Make sure we scrub the PEB in this case.
