[PATCH] init_task: Include <linux/rbtree.h> in the right file

[Christophe JAILLET]

There is no need to include <linux/rbtree.h> in init_task.h.
Move it to the right place, in kernel/cred.c which uses RB_ROOT_CACHED.

This is a follow-up of commit 4e7e3adbba52 ("Expand various INIT_* macros
and remove") which moved things from init_task.h to init_task.c

Let see if build-bots agree with me!

This patch depends on [1] and [2].
All these patches are related to init_task.h simplification.

They are unrelated and can be applied separately, but as they modify more
or less the same place in the same file, there may be some merge conflict.
