Subject: [PATCH] fs/ext4: remove unused variable 'de' in ext4_init_new_dir()

The variable 'de' was declared but never used in the ext4_init_new_dir()
function, causing a compiler warning:
variable 'de' set but not used [-Werror=unused-but-set-variable]
Remove the unused declaration to clean up the code and fix the warning.
