ext4: Change unsigned long to unsigned int
Convert the unsigned longs that are most responsible for bloating the stack usage on 64-bit systems. Nearly all places in the ext3/4 code which uses "unsigned long" is probably a bug, since on 32-bit systems a ulong a 32-bits, which means we are wasting stack space on 64-bit systems.
