can: isotp: isotp_setsockopt(): only allow to set low level TX flags for CAN-FD

Browse source

[ Upstream commit e4912459bd ]

CAN-FD frames have struct canfd_frame::flags, while classic CAN frames
don't.

This patch refuses to set TX flags (struct
can_isotp_ll_options::tx_flags) on non CAN-FD isotp sockets.

Fixes: e057dd3fc2 ("can: add ISO 15765-2:2016 transport protocol")
