libceph: put request only if it's done in handle_reply()
handle_reply() may be called twice on the same request: on ack and then
on commit. This occurs on btrfs-formatted OSDs or if cephfs sync write
path is triggered - CEPH_OSD_FLAG_ACK | CEPH_OSD_FLAG_ONDISK.
handle_reply() handles this with the help of done_request().
Fixes: 5aea3dcd5021 ("libceph: a major OSD client update")
