mm: introduce vma_get_page_prot() and use it
There's a large number of vm_get_page_prot(vma->vm_flags) invocations.
Make life easier by introducing vma_get_page_prot() parameterised by the
VMA.
This also makes converting vm_get_page_prot() to vma_flags_t easier.
Also update the userland VMA tests to reflect the change.
No functional change intended.
