In the j1939_xtp_rx_dat_one() function, there are 2 variables (skb and
se_skb) holding a skb. The control buffer of the skbs is accessed one
after the other, but using the same "skcb" variable.
To avoid confusion introduce a new variable "se_skcb" to access the
se_skb's control buffer as done in the rest of this file, too.
