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: 7158bee4b475 ("KVM: MMU: pass kvm_mmu_page struct to make_spte")
