Today, we don't track write-abiliy in the cache, if a user
requests a readable mapping followed by a writeable mapping
on the same page, the second lookup will incorrectly hit
the readable entry.
Split mapcache_grants by ro and rw access. Grants will now
have separate ways in the cache depending on writeability.
