mm: consolidate common checks in hugetlb_get_unmapped_area
prepare_hugepage_range() performs almost the same checks for all
architectures that define it, with the exception of mips and loongarch
that also check for overflows.
The rest checks for the addr and len to be properly aligned, so we can
move that to hugetlb_get_unmapped_area() and get rid of a fair amount of
duplicated code.
