Sean Christopherson c435d4b7ba KVM: x86/mmu: Properly dereference rcu-protected TDP MMU sptep iterator
Wrap the read of iter->sptep in tdp_mmu_map_handle_target_level() with
rcu_dereference().  Shadow pages in the TDP MMU, and thus their SPTEs,
are protected by rcu.

This fixes a Sparse warning at tdp_mmu.c:900:51:
  warning: incorrect type in argument 1 (different address spaces)
  expected unsigned long long [usertype] *sptep
  got unsigned long long [noderef] [usertype] __rcu *[usertype] sptep

Fixes: 7158bee4b4 ("KVM: MMU: pass kvm_mmu_page struct to make_spte")
