libceph: bump CEPH_PG_MAX_SIZE to 32
... to accommodate potentially very wide EC pools. This increases the size of a typical rbd ceph_osd_request by ~12% (from 1040 to 1168 bytes), but I'd rather go future proof here. Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Reviewed-by: Sage Weil <sage@redhat.com>
