Subject: [PATCH] ext4: fix build failure if DX_DEBUG

I got build failure when I turned on DX_DEBUG.

fs/ext4/namei.c: In function ‘dx_show_leaf’:
fs/ext4/namei.c:291: error: implicit declaration of function ‘ext4_next_entry’
fs/ext4/namei.c:291: warning: assignment makes pointer from integer without a cast

Move the definition of ext4_next_entry() upwards just as ext3 code.
