KVM: x86/mmu: pass struct kvm_pagewalk to kvm_mmu_invalidate_addr

kvm_mmu_invalidate_addr()'s callers only want to tell it whether to
invalidate a GVA or GPA.  This will ultimately be represented by two
different kvm_pagewalk structs, so adjust the type of the parameter.

As of this patch, the GVA case is represented by both root_mmu.w and
nested_mmu.w.  Since nested_mmu never has a sync_spte callback, it would
exit at its check, but really nested_mmu should not be a kvm_mmu in the
first place: it is only used as the walk_mmu, and walk_mmu is only used
for its struct kvm_pagewalk member.

Since calling container_of() on the nested_mmu would be bogus after it is
turned into a struct kvm_pagewalk, introduce a separate check to check
if no work is needed beyond kvm_x86_call(flush_tlb_gva).  Implement it
so that it is as similar as possible to what was happening until now; that
is, do nothing if the invalidation is happening for a nested GVA.
