can: j1939: j1939_send_one(): fix missing CAN header initialization
commit 3eb3d283e8579a22b81dd2ac3987b77465b2a22f upstream.
The read access to struct canxl_frame::len inside of a j1939 created
skbuff revealed a missing initialization of reserved and later filled
elements in struct can_frame.
This patch initializes the 8 byte CAN header with zero.
Fixes: 9d71dd0c7009 ("can: add support of SAE J1939 protocol")
