If we fail with a allocated hugepage, we need some effort to recover
properly. So, it is better not to allocate a hugepage as much as possible.
So move up anon_vma_prepare() which can be failed in OOM situation.

Although all articles declare that rcu read site is deadlock-immunity.
It is not true for rcu-preempt, it will be deadlock if rcu read site

If we fail with a reserved page, just calling put_page() is not sufficient,
because put_page() invoke free_huge_page() at last step and it doesn't
know whether a page comes from a reserved pool or not. So it doesn't do
anything related to reserved count. This makes reserve count lower

Current code include 'Caller expects lock to be held' in every error path.
We can clean-up it as we do error handling in one place.

vma_has_reserves() can be substituted by using return value of
vma_needs_reservation(). If chg returned by vma_needs_reservation()
is 0, it means that vma has reserves. Otherwise, it means that vma don't
have reserves and need a hugepage outside of reserve pool. This definition
is perfectly same
In order to validate that this failure is reasonable, we need to know
whether allocation request is for reserved or not on caller function.
So moving vma_needs_reservation() up to the caller of alloc_huge_page().
There is no functional change in this patch and following patch use
this information.
Currently, we have two variable to represent whether we can use reserved
page or not, chg and avoid_reserve, respectively. With aggregating these,
we can have more clean code. This makes no functinoal difference.

Now, alloc_huge_page() only return -ENOSPEC if failed.
So, we don't worry about other return value.

Just move down outside_reserve check and don't check
vma_need_reservation() when outside_resever is true. It is slightly
optimized implementation.
This makes code more readable.
