mm,hugetlb: split prep_new_huge_page functionality
Currently, prep_new_huge_page() performs two functions. It sets the
right state for a new hugetlb, and increases the hstate's counters to
account for the new page.
Let us split its functionality into two separate functions, decoupling
the handling of the counters from initializing a hugepage. The outcome
is having __prep_new_huge_page(), which only initializes the page , and
__prep_account_new_huge_page(), which adds the new page to the hstate's
counters.
This allows us to be able to set a hugetlb without having to worry about
the counter/locking. It will prove useful in the next patch.
prep_new_huge_page() still calls both functions.
