shmem: Fix link error if huge pages support is disabled
If CONFIG_TRANSPARENT_HUGE_PAGECACHE=n, HPAGE_PMD_NR evaluates to
BUILD_BUG_ON(), and may cause (e.g. with gcc 4.12):
mm/built-in.o: In function `shmem_alloc_hugepage':
shmem.c:(.text+0x17570): undefined reference to `__compiletime_assert_1365'
To fix this, move the assignment to hindex after the check for huge
pages support.
