  [b2b_entities] fix cseq to be used upon 200OK/CANCEL race

When generating the ACK+BYE upon 200 OK (from callee) racing a CANCEL (from caller), take care and use the correct cdeq values from the 200 OK (the b2b entity is not properly updated anymore, as it is already terminated by the CANCEL)

(cherry picked from commit a4e700d598c70caacf27c342b3c664ccfcf5ba5b)
