[PATCH v2 07/13] mm/vma: rename vma_get_page_prot to vma_flags_to_page_prot

[Lorenzo Stoakes]

Having vma_get_page_prot() refer to VMA flags and vma_set_page_prot() refer
to a VMA is confusing.

Rename vma_get_page_prot() to vma_flags_to_page_prot() to resolve this
confusion.

No functional change intended.
