Update amdp2ptest.h to sync with the same file from rdma test driver
folder.
Add ContiguousVRAMAllocation to verify rdma get pages will get
contiguous VRAM pages, skipped RDMA getpages if amdp2ptest.ko is not
loaded.
Change rdma buffer mmap with MAP_SHARED flag, because MAP_PRIVATE goes
to COW path, which requires mmap the entire vma and cannot support
multiple sg nents.
