[tcp] Mark SM as disabled prior resource binding

Browse source 
Otherwise we may send a SM ack request with the bind IQ request,
causing a stream error:

D/SMACK: SENT (0):
    <iq id='SETVB-74' type='set'>
      <bind xmlns='urn:ietf:params:xml:ns:xmpp-bind'>
      </bind>
    </iq>
    <r xmlns='urn:xmpp:sm:3'/>
D/SMACK: RECV (0):
    <iq id='SETVB-74' type='result'>
      <bind xmlns='urn:ietf:params:xml:ns:xmpp-bind'>
        <jid>
          snakeman@wiuwiu.de/eHeTGlCq
        </jid>
      </bind>
    </iq>
    <stream:error>
      <unsupported-stanza-type xmlns='urn:ietf:params:xml:ns:xmpp-streams'/>
    </stream:error>
    </stream:stream>
