arch/x86: teach arch_get_unmapped_area_vmflags to handle hugetlb mappings

Browse source

We want to stop special casing hugetlb mappings and make them go through
generic channels, so teach arch_get_unmapped_area_{topdown_}vmflags to
handle those.

x86 specific hugetlb function does not set either info.start_gap or
info.align_offset so the same here for compatibility.
