[RFC PATCH v2 06/20] powerpc/8xx: Fix size given to set_huge_pte_at()

[Christophe Leroy]

set_huge_pte_at() expects the real page size, not the psize which is
the index of the page definition in table mmu_psize_defs[]

Fixes: 935d4f0c6dc8 ("mm: hugetlb: add huge page size param to set_huge_pte_at()")
