[RFC PATCH 3/4] powerpc/mm/book3s: Check for pmd_large instead of pmd_trans_huge in set_pmd_at

["Aneesh Kumar K.V" <aneesh.kumar@linux.ibm.com>]

We want to use this to store swap pte at pmd level. For swap ptes we don't want
to set H_PAGE_THP_HUGE. Hence check for pmd_large in set_pmd_at. This remove
the false WARN_ON when using this with swap pmd entry.
