thp: fix PARAVIRT x86 32bit noPAE

Subject: thp: fix PARAVIRT x86 32bit noPAE
From: Andrea Arcangeli <aarcange@xxxxxxxxxx>
This fixes TRANSPARENT_HUGEPAGE=y with PARAVIRT=y and HIGHMEM64=n.
The #ifdef that this patch removes was erratically introduced to fix a
build error for noPAE (where pmd.pmd doesn't exist). So then the kernel
built but it failed at runtime because set_pmd_at was a noop. This will
correct it by enabling set_pmd_at for noPAE mode too.
