glusterd/geo-rep: Fix snapshot create in geo-rep setup

glusterd persists geo-rep sessions in glusterd
info file which is represented by dictionary
'volinfo->gsync_slaves' in memory. Glusterd also
maintains in memory active geo-rep sessions in
dictionary 'volinfo->gsync_active_slaves' whose key
is "<slave_url>::<slavhost>".

When glusterd is restarted while the geo-rep sessions
are active, it builds the 'volinfo->gsync_active_slaves'
from persisted glusterd info file. Since slave volume
uuid is added to "voinfo->gsync_slaves" with the commit
"http://review.gluster.org/13111", it builds it with key
"<slave_url>::<slavehost>:<slavevol_uuid>" which is
wrong. So during snapshot pre-validation which checks
whether geo-rep is active or not, it always says it is
ACTIVE, as geo-rep stop would not deleted this key.
Fixed the same in this patch.
