 This is for MythTV 0.27.1.

 I do have a CAM that unconditionally sends T_SB for tcid 2 on connection
 open which is not spec compliant. MythTV basically provisions for such
 cases in cCiTransportConnection::CreateConnection().

 However, cCiTransportConnection::RecvTPDU() breaks this as it
 unconditionally calls Init() on any "error", thus resetting the processing
 state from CREATION to IDLE.

 The attached patch fixes this for my case and should be seen as a sample
 workaround. Actually some interworking between CreateConnection() and
 RecvTPDU() is required to handle the retry cases in state CREATION
 properly.
