s_itb_per_group is defined to be an unsigned long, so a much better
fix is simply to change the format string.

Subject: [PATCH] ext4: fix compile warnings with EXT4FS_DEBUG enabled

Compile 2.6.38-rc1 with turning EXT4FS_DEBUG on,
we get following compile warnings. This patch fixes them.

  CC      fs/ext4/hash.o
  CC      fs/ext4/resize.o
fs/ext4/resize.c: In function 'setup_new_group_blocks':
fs/ext4/resize.c:233:2: warning: format '%#04llx' expects type 'long long
unsigned int', but argument 3 has type 'long unsigned int'
fs/ext4/resize.c:251:2: warning: format '%#04llx' expects type 'long long
unsigned int', but argument 3 has type 'long unsigned int'
  CC      fs/ext4/extents.o
