4.9-stable review patch. If anyone has any objections, please let me know.

From: Ilya Dryomov idryomov@gmail.com
Upstream commit cc255c76c70f ("libceph: implement CEPHX_V2 calculation mode") was adjusted incorrectly: CEPH_FEATURE_CEPHX_V2 if condition got inverted, thus breaking 4.9.144 and later kernels for all setups that use cephx.
