On sudden f2fs shutdown, write pointers of zoned block devices can go further but f2fs meta data keeps current segments at positions before the write operations. After remounting the f2fs, this inconsistency causes write operations not at write pointers and "Unaligned write command" error is reported. To avoid the error, compare current segments with write pointers of open zones the current segments point to, during mount operation. If the write pointer position is not aligned with the current segment position, assign a new zone to the current segment. Also check the newly assigned zone has write pointer at zone start. If not, reset write pointer of the zone. Perform the consistency check during fsync recovery. Not to lose the fsync data, do the check after fsync data gets restored and before checkpoint commit which flushes data at current segment positions. Not to cause conflict with kworker's dirfy data/node flush, do the fix within SBI_POR_DOING protection.
