IB/core: Fix build failure without hugepages
[ Upstream commit 74f75cda754eb69a77f910ceb5bc85f8e9ba56a5 ]
HPAGE_SHIFT is only defined on architectures that support hugepages:
drivers/infiniband/core/umem_odp.c: In function 'ib_umem_odp_get':
drivers/infiniband/core/umem_odp.c:245:26: error: 'HPAGE_SHIFT' undeclared (first use in this function); did you mean 'PAGE_SHIFT'?
Enclose this in an #ifdef.
Fixes: 9ff1b6466a29 ("IB/core: Fix ODP with IB_ACCESS_HUGETLB handling")
