Yonghua Huang 8a6e85f75a virt: acrn: obtain pa from VMA with PFNMAP flag ...

acrn_vm_ram_map can't pin the user pages with VM_PFNMAP flag
 by calling get_user_pages_fast(), the PA(physical pages)
 may be mapped by kernel driver and set PFNMAP flag.

 This patch fixes logic to setup EPT mapping for PFN mapped RAM region
 by checking the memory attribute before adding EPT mapping for them.
