bpf: pass reason for TO_NETDEV through host firewall
bpf: pass reason for TO_NETDEV through host firewall

In bpf_host's to_netdev()'s call to send_trace_notify() we do not only
want to have the monitor parameter that has been populated by the host
firewall's CT lookup, but also the trace reason from it. The previous
commit gave it to us for free, let's just add the reason to the traces.

Fixes: #18460
