KVM: x86/mmu: Use common logic for computing the 32/64-bit base PA mask
Use common logic for computing PT_BASE_ADDR_MASK for 32-bit, 64-bit, and
EPT paging. Both PAGE_MASK and the new-common logic are supsersets of
what is actually needed for 32-bit paging. PAGE_MASK sets bits 63:12 and
the former GUEST_PT64_BASE_ADDR_MASK sets bits 51:12, so regardless of
which value is used, the result will always be bits 31:12.
No functional change intended.
