dax: Convert dax_insert_pfn_mkwrite to XArray
Add some XArray-based helper functions to replace the radix tree based
metaphors currently in use. The biggest change is that converted code
doesn't see its own lock bit; get_unlocked_entry() always returns an
entry with the lock bit clear. So we don't have to mess around loading
the current entry and clearing the lock bit; we can just store the
unlocked entry that we already have.
