IB/core: Fix build failure without hugepages

Browse source 
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: 9ff1b6466a ("IB/core: Fix ODP with IB_ACCESS_HUGETLB handling")
