mlxsw: spectrum_flower: Forbid to offload mirred redirect on egress
Spectrum ASIC does not support redirection on egress, so refuse to
insert such flows:
$ tc qdisc add dev ens16np1 clsact
$ tc filter add dev ens16np1 egress protocol all pref 1 handle 101 flower skip_sw action mirred egress redirect dev ens16np2
Error: mlxsw_spectrum: Redirect action is not supported on egress.
