Revert the change done to oscam-emm.c on 11806 back to the previous state.

It has turned out that the change implemented on 11806 just only working for local au on Tivusat 1856 and HD04H cards only. This is because the variable reader->cak7_emm_caid doesn't get sent to network protocol reader. In order to get the variable reader->cak7_emm_caid sent to network protocol reader, all oscam protocols must be modified, hence the serious compatibility issue could have occurred as some other closed linux box, which has CCCam or NewCand, might struggle to communicate with oscam that has protocols modified. Therefore, I have made the decision to revert the oscam-emm.c implementation on 11806 in order to solve all issues.
