[ATM]: Fix dereference of uninitialized pointer in zatm
Fixing breakage from [NET]: Kill skb->list - original was assign vcc do a bunch of stuff using ZATM_VCC(vcc)->pool as common subexpression Now we do int pos = ZATM_VCC(vcc)->pool; assign vcc do a bunch of stuff even though vcc is not even initialized when we enter that block...
