KVM: x86/mmu: pull struct kvm_pagewalk out of struct kvm_mmu

Replace kvm_mmu's w field with a pointer to an external instance of
struct kvm_pagewalk.  This is the first step towards using a single
kvm_pagewalk struct for all GVA walks, whether nested or not.

With this patch, non-MMU code basically does not use kvm_mmu anymore:
it does care about page walks, but it funnels (almost) all interactions
with the TLB to mmu.c.

kvm_mmu_invalidate_addr() still needs to go from kvm_pagewalk to kvm_mmu,
and it cannot anymore use container_of() to do it; the mapping is hardcoded
based on the provided kvm_pagewalk, since there are just three of them.
