KVM: RISC-V: Mark "struct page" pfns dirty iff a stage-2 PTE is installed
Don't mark pages dirty if KVM bails from the page fault handler without
installing a stage-2 mapping, i.e. if the page is guaranteed to not be
written by the guest.
In addition to being a (very) minor fix, this paves the way for converting
RISC-V to use kvm_release_faultin_page().
