Remove the net_device string name from the xdp_exception tracepoint,
like the xdp_redirect tracepoint.

Align the TP_STRUCT to have common entries between these two
tracepoint.

If you already get them in sync, could you also make it consistent

directly or device pointer and extract it from TP_fast_assign().
Right now, it's mixed.
