Subject: [ 077/171] ceph: use info returned by get_authorizer

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

------------------

From: Alex Elder <elder@...tank.com>

(cherry picked from commit 8f43fb53894079bf0caab6e348ceaffe7adc651a)

Rather than passing a bunch of arguments to be filled in with the
content of the ceph_auth_handshake buffer now returned by the
get_authorizer method, just use the returned information in the
caller, and drop the unnecessary arguments.
