x86: put_superpage() must also work for !opt_allow_superpage
This is because the P2M table, when placed at a kernel specified
location, gets populated with large pages, which the domain must have
a way to unmap/recycle.
Additionally when allowing Dom0 to use superpages, they ought to be
tracked accordingly in the superpage frame table.
