KVM: RISC-V: Mark "struct page" pfns accessed before dropping mmu_lock

Mark pages accessed before dropping mmu_lock when faulting in guest memory
so that RISC-V can convert to kvm_release_faultin_page() without tripping
its lockdep assertion on mmu_lock being held.  Marking pages accessed
outside of mmu_lock is ok (not great, but safe), but marking pages _dirty_
outside of mmu_lock can make filesystems unhappy (see the link below).
Do both under mmu_lock to minimize the chances of doing the wrong thing in
the future.
