KVM: x86/mmu: Use gfn_to_page_many_atomic() when prefetching indirect PTEs
Use gfn_to_page_many_atomic() instead of gfn_to_pfn_memslot_atomic() when
prefetching indirect PTEs (direct_pte_prefetch_many() already uses the
"to page" APIS). Functionally, the two are subtly equivalent, as the "to
pfn" API short-circuits hva_to_pfn() if hva_to_pfn_fast() fails, i.e. is
just a wrapper for get_user_page_fast_only()/get_user_pages_fast_only().
Switching to the "to page" API will allow dropping the @atomic parameter
from the entire hva_to_pfn() callchain.
