jbd: Journal block numbers can ever be only 32-bit use unsigned int for them
It does not make sense to store block number for journal as unsigned long since they can be only 32-bit (because of on-disk format limitation). So change in-memory structures and variables to use unsigned int instead. Signed-off-by: Jan Kara <jack@suse.cz>
