KVM: MMU: Replace role.glevels with role.cr4_pae
There is no real distinction between glevels=3 and glevels=4; both have
exactly the same format and the code is treated exactly the same way. Drop
role.glevels and replace is with role.cr4_pae (which is meaningful). This
simplifies the code a bit.
As a side effect, it allows sharing shadow page tables between pae and
longmode guest page tables at the same guest page.
