mm: convert __get_unmapped_area() to use vma_flags_t
Update __get_unmapped_area() to be parameterised by vma_flags_t rather
than vm_flags_t as part of the effort to move VMA flags from a system word
to a bitmap.
We cascade the changes up to arch_get_unmapped_area_topdown() and
arch_get_unmapped_area(), where, for now, we use vma_flags_to_legacy() in
order to propagate the VMA flags.
No functional change intended.
