jbd: Journal block numbers can ever be only 32-bit use unsigned int for them

Browse Source 
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.
