vfio: cpu: Use "real" page size API

Browse Source 
This is system level code, and should only depend on the host page
size, not the target page size.

Note that HOST_PAGE_SIZE is misleadingly lead and is really aligning
to both host and target page size. Hence it's replacement with
REAL_HOST_PAGE_SIZE.
