Commit a774f9c2 "ext4: make ext4_init_dot_dotdot for inline dir usage"
is a preparation cleanup for later ext4 patches but there was a snag
when moving code to the newly created ext4_init_new_dir() function.
ext4_bread() is called twice but brelse() is only called one leading to a
memory leak. The user-visible effect is that after a compile-orientated
benchmark 0% of memory could be allocated as transparent huge pages.
This patch deletes the extra call and after it is applied, 76% of memory
could be allocated after the same test.
