mm/shmem: fix build without THP
Some optimizers don't notice that shmem_punch_compound() is always true
(PageTransCompound() being false) without CONFIG_TRANSPARENT_HUGEPAGE==y.
Use IS_ENABLED to help them to avoid the BUILD_BUG inside HPAGE_PMD_NR.
Fixes: 71725ed10c40 ("mm: huge tmpfs: try to split_huge_page() when punching hole")
