Patch from Andreas Dilger <adilger@clusterfs.com>

This patch against 2.5.53 removes my erronous use of ino_t in a couple of
places in the ext3 code.  This has been replaced with unsigned long (the same
as is used for inode->i_ino).  This patch matches the fix submitted to 2.4
for fixing 64-bit compiler warnings, and also replaces a couple of %ld with
%lu to forestall output wierdness with filesystems with a few billion inodes.
