KVM: Handle partial pae pdptr

Browse source

Some guests (Solaris) do not set up all four pdptrs, but leave some invalid.
kvm incorrectly treated these as valid page directories, pinning the
wrong pages and causing general confusion.

Fix by checking the valid bit of a pae pdpte.  This closes sourceforge bug
1698922.
