If a page mapping fails when mapping several pages in a single write bio
request, make sure that already mapped pages are invalidated. Since
other legit mappings coming from a different bio request might have
occurred, rolling back the failed bio is a difficult, unnecessary
overhead; in part because when a mapping fails something bad has
happened already. Still, invalidating pages in the failed bio will help
GC.
