KVM: x86/mmu: Split out TDP MMU page fault handling

Split out the page fault handling for the TDP MMU to a separate
function.  This creates some duplicate code, but makes the TDP MMU fault
handler simpler to read by eliminating branches and will enable future
cleanups by allowing the TDP MMU and non-TDP MMU fault paths to diverge.

Only compile in the TDP MMU fault handler for 64-bit builds since
kvm_tdp_mmu_map() does not exist in 32-bit builds.

No functional change intended.
