Alexandre Ghiti cc698db49b riscv: Fix build error if !CONFIG_ARCH_ENABLE_HUGEPAGE_MIGRATION ...

[ Upstream commit fc325b1a915f6d0c821bfcea21fb3f1354c4323b ]

The new riscv specific arch_hugetlb_migration_supported() must be
guarded with a #ifdef CONFIG_ARCH_ENABLE_HUGEPAGE_MIGRATION to avoid
the following build error:
