mm: update all remaining mmap_prepare users to use vma_flags_t
We will be shortly removing the vm_flags_t field from vm_area_desc so we
need to update all mmap_prepare users to only use the dessc->vma_flags
field.
This patch achieves that and makes all ancillary changes required to make
this possible.
This lays the groundwork for future work to eliminate the use of
vm_flags_t in vm_area_desc altogether and more broadly throughout the
kernel.
While we're here, we take the opportunity to replace VM_REMAP_FLAGS with
VMA_REMAP_FLAGS, the vma_flags_t equivalent.
No functional changes intended.
