KVM: x86/mmu: Factor out tdp_iter_return_to_root
In tdp_mmu_iter_cond_resched there is a call to tdp_iter_start which causes the iterator to continue its walk over the paging structure from the root. This is needed after a yield as paging structure could have been freed in the interim. The tdp_iter_start call is not very clear and something of a hack. It requires exposing tdp_iter fields not used elsewhere in tdp_mmu.c and the effect is not obvious from the function name. Factor a more aptly named function out of tdp_iter_start and call it from tdp_mmu_iter_cond_resched and tdp_iter_start. No functional change intended.
