This patch updates the L2CAP Channel state to Connected when LE Link
is established, so that data transmission can start on CID 4.
Without this fix if remote side sends data on CID 4 immidiately after
LE Link was established, data was being discarded in l2cap_att_channel()
API because channel state was still BT_CONNECT when SMP pairing is in
progress. This was resulting in disconnection from remote side after 30 seconds
since ATT request was not answered by user space as data was discarded.
