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.

Want to use two-tab indentation while at it?

Yeah sure will fix on respin!
