KVM: x86/mmu: Initialize fault.{gfn,slot} earlier for direct MMUs

Browse source

Move the initialization of fault.{gfn,slot} earlier in the page fault
handling code for fully direct MMUs. This will enable a future commit to
split out TDP MMU page fault handling without needing to duplicate the
initialization of these 2 fields.

Opportunistically take advantage of the fact that fault.gfn is
initialized in kvm_tdp_page_fault() rather than recomputing it from
fault->addr.

No functional change intended.
