can: j1939: j1939_session_new(): fix skb reference counting

In the Linux kernel, the following vulnerability has been resolved:

can: j1939: j1939_session_new(): fix skb reference counting

Since j1939_session_skb_queue() does an extra skb_get() for each new
skb, do the same for the initial one in j1939_session_new() to avoid
refcount underflow.
