    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.
