mlxsw: spectrum: Veto sampling if already enabled on port
The per-port sampling triggers (i.e., ingress / egress) cannot be
enabled twice. Meaning, the below configuration will not result in
packets being sampled twice:
# tc filter add dev swp1 ingress matchall skip_sw action sample rate 100 group 1
# tc filter add dev swp1 ingress matchall skip_sw action sample rate 100 group 1
Therefore, reject such configurations.
