[PATCH RFC v2 04/20] LoongArch: mm: define pud_leaf() only when PUD exists

[Yeoreum Yun]

From: "David Hildenbrand (Arm)" <david at kernel.org>

In include/asm-generic/pgtable-nopmd.h, we do have a hard-coded
pud_leaf()=false inline function, but we miss the "define pud_leaf
pud_leaf" part.

To prepare for fixing that, define pud_leaf() only if we don't have
__PAGETABLE_PMD_FOLDED.
