OSCAM with No CW Swap for 09CD

[gb21063]

CW OK => 6045640931EE7C9B0000000000000000 => count 11
CW BAD => 0000000000000000F6488AC8076BB123 => count 13

Oscam swap the cw from 0000000000000000F6488AC8076BB123 to this
2014/02/08 01:01:34 E04F1DF0 c dreambox (09CD&000000/04C0/2BD0/B7/F8BFE7EC/F6488AC8076BB1230000000000000000): cache3 (220 ms) by peerA (cw count 11)


give cw OK but cw is not valid, result 10 second freeze. Without swap the cyclecheck will detect the invalid cw, and goes to another reader. Normaly this happens, but in cwc if the 0 byte of cw is not right, oscam gives a cwc IGN without asking another reader:

(cwc *** IGN) should be (cwc *** NOK) to ask another reader.
