xfstests generic/482 tests the file system consistency after each FUA operation. It fails when run on exfat. exFAT clears the volume dirty flag with a FUA operation during sync. Since s_lock is not held when data is being written to a file, sync can be executed at the same time. When data is being written to a file, the FAT chain is updated first, and then the file size is updated. If sync is executed between updating them, the length of the FAT chain may be inconsistent with the file size. To avoid the situation where the file system is inconsistent but the volume dirty flag is cleared, this commit moves the clearing of the volume dirty flag from exfat_fs_sync() to exfat_put_super(), so that the volume dirty flag is not cleared until unmounting. After the move, there is no additional action during sync, so exfat_fs_sync() can be deleted.
