  File "/usr/share/glusterfs/scripts/schedule_georep.py", line 342, in get_summary

COMMIT: https://review.gluster.org/19991 committed in master by "Kotresh HR" <khiremat> with a commit message- geo-rep/scheduler: Fix crash

Fix crash where session_name is referenced
before assignment. Well, this is a corner
case where the geo-rep session exists and
the status output doesn't show any rows.
This might happen when glusterd is down
or when the system is in inconsistent state
w.r.t glusterd.
