To catch f2fs bugs in write pointer handling code for zoned block devices, check write pointers of non-open zones that current segments do not point to. Do this check at mount time, after the fsync data recovery and current segments' write pointer consistency fix. Or when fsync data recovery is disabled by mount option, do the check when there is no fsync data. Check two items comparing write pointers with valid block maps in SIT. The first item is check for zones with no valid blocks. When there is no valid blocks in a zone, the write pointer should be at the start of the zone. If not, next write operation to the zone will cause unaligned write error. If write pointer is not at the zone start, reset the write pointer to place at the zone start. The second item is check between the write pointer position and the last valid block in the zone. It is unexpected that the last valid block position is beyond the write pointer. In such a case, report as a bug. Fix is not required for such zone, because the zone is not selected for next write operation until the zone get discarded.
