Although harmless in functionality not having it, may be it would be
good to also apply with this also the following commit:

commit 261030215d970c62f799e6e508e3c68fc7ec2aa9

libceph: drop declaration of ceph_con_get()

For some reason the declaration of ceph_con_get() and
ceph_con_put() did not get deleted in this commit:
d59315ca libceph: drop ceph_con_get/put helpers and nref member

Clean that up.
