Move the call to kvm_mmu_hugepage_adjust() up to the fault handler
rather than calling it from kvm_tdp_mmu_map(). Also make the same change
to direct_map() for consistency. This reduces the TDP MMU's dependency
on an x86-specific function, so that it can be moved into common code.
No functional change intended.
