[PATCH 2/8] KVM: VMX: Refactor 32-bit PSE PT creation to avoid using MMU macro

[Sean Christopherson <seanjc@google.com>]

Compute the number of PTEs to be filled for the 32-bit PSE page tables
using the page size and the size of each entry.  While using the MMU's
PT32_ENT_PER_PAGE macro is arguably better in isolation, removing VMX's
usage will allow a future namespacing cleanup to move the guest page
table macros into paging_tmpl.h, out of the reach of code that isn't
directly related to shadow paging.

No functional change intended.
